Question

please selecte the true following statements

1 - temperature is the flow of heat energy from one object to another
2 - heat is the transfer of energy from one higher temperature object to a lower temperature object.
3 - temperature can flow from one object to another
4 - when temperature changes, objects can change states.
5 - when heat flows from an object , it can change states.

Answer 1

Let's evaluate each statement:

1. **Temperature is the flow of heat energy from one object to another.**
- **False**: Temperature is a measure of the average kinetic energy of the particles in a substance, not the flow of heat.

2. **Heat is the transfer of energy from one higher temperature object to a lower temperature object.**
- **True**: Heat does flow from hot (higher temperature) objects to cold (lower temperature) objects.

3. **Temperature can flow from one object to another.**
- **False**: Temperature itself does not flow; instead, heat is the energy that flows due to a temperature difference.

4. **When temperature changes, objects can change states.**
- **True**: A change in temperature can lead to a change in the state of matter, such as melting or boiling.

5. **When heat flows from an object, it can change states.**
- **True**: When heat is removed from an object (for example, cooling), the object can change states, such as freezing a liquid to a solid.

The true statements are: **2, 4, and 5.**
