QuestionAnswer
How does heat flow? Hot to cold
Kinetic Molecular Model= All particles are in constant motion, thus they have have kinetic energy.
Internal Energy= Sum of all PE and KE in an object
Thermall Energy is measured when it is transferred from ojne system to another
Heating and Cooling are the action of transferring particle kinetic energy
A loss of thermal energy is accompanied by a fall in temperature
A gain in thermal energy is accompanied by a rise in temperature
The temperature of an object is directly related to the average kinetic energy of the object
in 1714, the first temperature scale was created by Gabriel Farenheit
In 1742, the second scale was invented by Anders Celcius
In 1848, ______ created the final scale Lord Kelvin
Thermal Expansion happens on the _____level particle
Electrical Resistance increases with temperature because the particles move more randomly
Viscosity is the measure of the resistance that liquids exert
Heat is the quantity of thermal energy that flows from one place to another
Conduction= when two objects of unequal temperature touch, thermal energy moves form the hotter object to the cooler one
Thermal Equillibrium is when two objects have the same temperature
Conduction is for solids
Convection is for liquids
Radiation is for waves
Specific Heat the heat capacity per gram in the material
Specific heat formula= Q=cmt
Sublimation is when a solid id transformed to a gas
Deposition is when gas is transformed to a solid
Triple Point Temp at which a solid, liquid, and gas can exist simultaneously
Critical Point point where a substance will always be a gas no matter what the pressure is

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
