Radiation
Absorption
2. Thermal equilibrium is reached when:
Heat transfer stops completely.
The net heat transfer between objects is zero.
All objects have the same internal energy.
The temperature of all objects becomes absolute zero.
3. The transfer of heat through direct contact is called .
4. Dark, dull surfaces are good of thermal radiation.
5. The amount of heat required to raise the temperature of 1 kg of a substance by 1°C is its .
6. Heat always flows from a colder object to a hotter object.
True
False
7. A vacuum can effectively transfer heat by convection.
True
False
8. Explain the difference between heat and temperature.
9. Describe a real-world example of heat transfer by radiation.
10. A 0.5 kg aluminum block (specific heat = 900 J/kg°C) at 100°C is placed in 1.0 kg of water (specific heat = 4186 J/kg°C) at 20°C. Assuming no heat loss to the surroundings, calculate the final equilibrium temperature of the system.
