Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following best defines specific heat capacity?
The amount of heat required to change the temperature of 1 kg of a substance by 1 °C.
The total heat content of a substance.
The rate at which a substance absorbs heat.
The temperature at which a substance melts.
2. Water has a high specific heat capacity. This property is important because:
It allows water to freeze quickly.
It helps regulate Earth's climate.
It makes water a good electrical conductor.
It causes water to evaporate rapidly.
3. The formula used to calculate the amount of heat energy transferred is Q = m c ΔT, where Q is the heat energy, m is the mass, c is the , and ΔT is the change in temperature.
4. Substances with a low specific heat capacity heat up and cool down than substances with a high specific heat capacity.
5. A 500 g iron block (specific heat = 450 J/kg°C) is heated from 20°C to 80°C. Calculate the amount of heat absorbed by the iron block.
6. Explain why coastal regions tend to have more moderate climates than inland regions.
7. Specific heat capacity is an intensive property, meaning it does not depend on the amount of substance.
True
False
8. The units for specific heat capacity are typically Joules per gram per degree Celsius (J/g°C).
True
False
Match the term on the left with its description on the right.
9. Calorimetry
a. The amount of heat required to raise the temperature of a substance by 1 °C.
10. Heat
b. The process of measuring the amount of heat released or absorbed during a chemical reaction or physical change.
11. Enthalpy
c. A form of energy that is transferred between objects due to a temperature difference.
12. Heat Capacity
d. The total heat content of a system at constant pressure.
13. A solar water heater uses the Sun's energy to heat water. Explain how the high specific heat capacity of water makes it an ideal substance for this application.
