Which of the following is a relative measure or indication of hotness or coldness?

Options

A. Heat
B. Temperature
C. Energy
D. All of these

Answer

To solve the question "Which of the following is a relative measure or indication of hotness or coldness?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for a relative measure of hotness or coldness. This means we need to identify a term or concept that allows us to compare the thermal states of different objects.

2. **Consider the Options**: Although the options are not provided in the question, we can infer that common terms related to thermal properties might include temperature, heat, thermal energy, and others.

3. **Define Temperature**: Temperature is defined as a measure of the average kinetic energy of the particles in a substance. It is a quantitative measure that indicates how hot or cold an object is relative to another object.

4. **Identify the Relative Nature of Temperature**: Temperature allows us to compare two or more objects. For example, if one object has a higher temperature than another, we can say it is hotter. Conversely, if it has a lower temperature, it is cooler. This relative comparison is what makes temperature a measure of hotness or coldness.

5. **Conclusion**: Based on the definition and understanding of temperature, we conclude that temperature is indeed the correct answer as it is a relative measure of hotness or coldness.

### Final Answer:
The correct option is **Temperature**.
