Question: 32 Celsius in Fahrenheit Answer: 90 Fahrenheit
Question: 20 Celsius in Fahrenheit Answer: 68 Fahrenheit
Question: -20 Celsius in Fahrenheit Answer: -4 Fahrenheit
Question: Density of an object is 17 g/mL and has a mass of 34 g. What is the volume of the object? Answer: 2 mL
Question: You have two objects: Object A has a mass of 4g and volume of 2mL. Object B has a mass of 15 g and volume of 5 mL. Which object would float in a liquid with a density of 2.5 g/mL? Answer: Object A would float (density = 2 g/mL). Object B would sink (3 g/mL).
Question: What is the volume of a box that has the following dimensions? 9 cm long, 5 cm tall, 3 cm wide Answer: 135 cm^3
Question: What is the density of a box with a volume of 412 cm^3 and a mass of 42 g? 0.102 g/cm^3
Question: You have an egg with a density of 1.03 g/mL. Will it float or sink in the Chesapeake Bay? Answer: It will sink in the Chesapeake Bay, which has a brackish estuary mix of seawater (1.03 g/mL) and fresh water (1.0 g/mL).
Question: What is the name of the layer between fresh water and salt water? Answer: Halocline (halo = salt, cline = boundary)
Question: What is the changing balance of salt water and fresh water in the Chesapeake Bay called - the scientific words. Answer: Dynamic Equilibrium
Question: Calculate the density of a 500 g rectangular rock with dimensions of length = 8 cm, width = 6 cm, height = 5 cm. Answer: 2.08 g/cm^3
Question: You go swimming in the Dead Sea, which has a whopping density of 1.24 g/mL. You checked your scale recently and weighed in at 70,000 g. What does your minimum volume need to be in order to float in the Dead Sea? Answer: 56,451 mL or 56.5 L (You'll probably float - that puts you right at the same density, so you still may need more volume)
Question: The Mediterranean Sea has a salinity of 38 ppt and temperature of 16 Celsius. Would Pacific Ocean Sea water float or sink when added to a cup of Mediterranean Sea Water? Answer: Float - Pacific Ocean water is less saline and therefore less dense. Pacific water would need to be cooled considerably in order to make it sink.
Question: A Blue sample of water has a salinity of 33 ppt and temperature of 10 Celsius. A Yellow sample of water has a salinity of 34 ppt and a temperature of 15 Celsius. Which sample would float on top? Answer: Neither. Both have a density of slightly lower than 1.0255 according to the TDS chart.
Question: You have a Warm sample of Brackish water and a Cold sample of Atlantic Ocean water. What is the name of the layer between the samples of water? Answer: Pycnocline - there is a density gradient that is made up of both temperature and salinity differences.
Question: The Pacific Ocean has lower salinity near the poles and at the equator. Why is the salinity so much lower near the poles? Answer: Freshwater runoff due to glacial and polar ice cap melt
Question: You put an object of 1 g/mL into a fluid with a density of 3 g/mL. Will the object float or sink? Answer: Object will float because the density is lower.
Question: You put an object with a density of 4.17 g/mL into a fluid with a density of 4.17 g/mL. What will happen to the object? Answer: Object will neither float nor sink - it will bob around in the fluid, but not rest on the bottom or at the top of the water.
Question: You have 30 mL of water into which you drop a crystal that brings the water level to 35 mL. The mass of the graduated cylinder was 40 g before the object was added and 58 g after. Could this crystal be a diamond?! diamond = 3.55 g/cm^3 Answer: Yes, it could be! Volume = 5 mL Mass = 18 g Density = 3.6 g/mL
Question: You drop a rock into water and the rock sinks. What can you Infer from this? Answer: The rock's density is greater than 1.0 g/mL (water).
Question: You drop a rock into water and the rock floats. What can you infer from this? Answer: The rock's density is less than 1.0 g/mL (water). You might even know that the only rocks that float are volcanic extrusive in origin - pumice & scoria are full of air pockets!
Question: What density is water with a Salinity of 35 ppt ad a temperature of 10 Celsius? Answer: Density from TDS chart is 1.0270 g/mL
Question: What temperature is water with a density of 1.0255 g/mL and a salinity of 34 ppt? Answer: Temperature from TDS chart is 14 Celsius. (You don't get to claim it if you said 15!)
Question: What is the salinity of water with a density of 1.0235 g/mL and a temperature of 19.5 Celsius? Answer: Salinity is 33.0 ppt.
Question: Water has a salinity of 32.5 ppt and density is currently 1.0245 g/mL. What is the temperature in Fahrenheit? Answer: Celsius temperature is 12. This converts to 53.6 Fahrenheit.
Question: If you have a sample of warm water (dyed red) and cold water (dyed blue), which would layer on top? Answer: Warm water - it is less dense than cold water and will move to the top if the temperature gradient is significant
Question: What are the three factors that affect the density of an object. Answer: Atomic mass, temperature, and pressure
Question: Water at the bottom of the ocean has a temp of about 2 Celsius. Would that water be more of less dense than a cup of ice water at 2 Celsius in the classroom? Answer: Water at bottom of ocean is more dense due to the pressure of the water column above.
Question: What causes water to rise up from the ocean floor? Answer: When deep water currents collide with continents they create upwelling.
Question: What type of Circulation causes the movement of the Great Ocean Conveyor Belt? Answer: Thermohaline Circulation (Thermo = heat, haline = salt)
Question: Insolation creates what kind of differences on Earth's surface? Answer: Temperature differences. Insolation is heat from the sun , which strikes the earth directly at the equator (high insolation) and at an angle at the poles (low insolation).
Question: What type of body of water is the Chesapeake Bay? Answer: Estuary
Question: Where does most of the water in the Chesapeake Bay come from? Answer: Susquehanna River
Question: Some years the salinity of the bay is very high, what weather conditions could cause this? Answer: Very dry years with little precipitation.
Question: Some years the salinity in the Chesapeake Bay is very low, what weather conditions could cause this? Answer: Very wet years with a great deal of precipitation.
Question: The dynamic equilibrium in the Chesapeake Bay is due primarily to what two factors? Answer: Freshwater inflow and Tidal Inflow from the Atlantic Ocean
Question: Where does the Great Ocean Conveyor Belt begin? Answer: At the poles - dense cold, salty water sinks at both the North and South poles.
Question: What type of energy transfer is driving Thermohaline circulation? Answer: Convection
Question: What causes the Ocean to stratify? Answer: Density gradients between warm, less salty water and cold, more salty water.
Question: What could cause Thermohaline Circulation to stop? Answer: If the Poles were to stop freezing, Global Warming, or Climate Change are three possible answers
Question: Where are the Ocean temperatures highest? Answer: Near the Equator
Question: What are the five tributary rivers of the Chesapeake Bay? Answer: Susquehanna, Potomac, Rappahannock, York, James
Question: 35.5 Million Years ago what event created the Chesapeake Bay? Answer: Meteorite Impact
Question: What part of the water cycle is evaporation through tree respiration? Answer: Transpiration
Question: What part of the water cycle washes nutrients like Phosphates and Nitrates into the Chesapeake bay, causing Algal Blooms? Answer: Runoff
