An example of good conductor of heat is

Options

A. wood
B. cork
C. copper
D. glass

Answer

To solve the question "An example of a good conductor of heat is," we can follow these steps:

### Step 1: Understand the Concept of Thermal Conductivity
- **Explanation**: Thermal conductivity is a measure of a material's ability to conduct heat. Materials with high thermal conductivity are considered good conductors of heat.

### Step 2: Identify Good Conductors of Heat
- **Explanation**: Metals are generally known to be good conductors of heat due to their free-moving electrons, which facilitate the transfer of thermal energy. Non-metals, on the other hand, typically have lower thermal conductivity.

### Step 3: Analyze the Options Provided
- **Explanation**: If options are given (though not specified in the question), identify which ones are metals and which are non-metals. Metals like copper, aluminum, and silver are excellent conductors of heat.

### Step 4: Select the Correct Answer
- **Explanation**: Based on the analysis of the options, choose the one that is a metal, as it will be the best example of a good conductor of heat.

### Conclusion
- The correct answer to the question is the metal option provided in the choices.
