1. What is the primary purpose of a calorimeter?
To measure mass
To measure temperature changes
To measure heat absorbed or released
To measure volume
2. Which of the following is an essential component of a simple calorimeter?
A heating plate
An insulated container

3. The principle behind calorimetry is the conservation of .
4. The specific heat capacity (c) of a substance is the amount of required to raise the temperature of 1 gram of the substance by 1 degree Celsius.
5. Describe the basic function of a calorimeter.
6. Explain why insulation is crucial for a calorimeter to work effectively.
7. In an ideal calorimeter, there is no heat exchange with the surroundings.
True
False
8. A substance with a high specific heat capacity will heat up and cool down quickly.
True
False
9. A 50.0 g sample of metal at 100.0 °C is placed in a calorimeter containing 100.0 g of water at 25.0 °C. The final temperature of the water and metal is 28.5 °C. If the specific heat capacity of water is 4.18 J/g°C, calculate the specific heat capacity of the metal. Assume no heat loss to the surroundings.
