Chemistry OYO

Module 2 - OYO

QuestionAnswer
2.1 Normal body temperature is 98.6 °F. What is this temperature in Celsius? 37.0 °C
2.2 If water boils at 100.0 °C, what is the boiling temperature of water in Fahrenheit? 212.0 °F
2.3 What is the Fahrenheit equivalent of 0.00 Kelvin? -459.67 °F
2.4 Which substance takes the least energy to heat up, copper or glass? (refer to Table 2.1) Copper.
2.5 A copper kettle and an iron kettle are placed side by side on a fire. After 3.0 minutes on the fire, the iron kettle reaches a temperature of 100.0 °C. Will the copper kettle's temperature be higher or lower than 100.0 °C? (refer to Table 2.1) Higher.
2.6 A 502 g iron rod is heated to an unknown initial temperature. If, while cooling down to a temperature of 22 °C, the rod releases 597.5 Joules of energy, what was its initial temperature? 25 °C
2.7 If a 15.6 g object requires 836.8 J of heat to raise its temperature by 21 °C, what is the specific heat of the object? 2.6 J per g·°C
2.8 A calorimeter holds 175.0 grams of water at an initial temperature of 25.3 °C. A 54.3 g piece of metal at 100.0 °C is dropped into the calorimeter, and the final temperature of the water is 27.1 °C. What is the specific heat of the metal? 0.33 J per g·°C
2.9 A calorimeter holds 100.0 grams of water at an initial temperature of 25.1 °C. A 43.2 g piece of metal at 111.0 °C is dropped into the calorimeter, and the final temperature of the water is 29.1 °C. What is the specific heat of the metal? 0.51 J per g·°C
2.10 A calorimetry experiment is performed with a calorimeter that has a specific heat of 3.77 J per g·°C. The calorimeter has a mass of 9.5 g and is filled with 117 g of an unknown liquid that is initially at a temperature of 25.0 °C.
2.10(continued) If a 50.0 g chunk of copper at 112 °C is dropped in the calorimeter and the liquid's temperature increases by 2.3 °C, what is the specific heat of the unknown liquid? 5.75 J per g·°C
