Question

please select all true statements

1 - a warm object in a cool environment will, overall, release energy
2 - a warm object in a cool environment will, overall, gain energy
3 - a cool object in a warm environment will, overall, gain energy
4 - a cool object in a warm environment will, overall, release energy
5 - at equilibrium, energy is equally gained and released by objects.

Answer 1

Let's evaluate each statement one by one:

1. **A warm object in a cool environment will, overall, release energy.**
- **True**: A warm object will lose energy (typically in the form of heat) to the cooler surroundings.

2. **A warm object in a cool environment will, overall, gain energy.**
- **False**: A warm object is losing energy to the cooler environment, not gaining.

3. **A cool object in a warm environment will, overall, gain energy.**
- **True**: A cooler object will absorb heat from the warmer surroundings, gaining energy.

4. **A cool object in a warm environment will, overall, release energy.**
- **False**: A cool object will not release energy in a warm environment; instead, it absorbs energy.

5. **At equilibrium, energy is equally gained and released by objects.**
- **True**: At thermal equilibrium, there is no net transfer of energy between objects; they are gaining and losing energy at equal rates.

**Summary of true statements:** 1, 3, and 5.
