Question

Suppose a body A at a higher temperature is brought into contact with another body B at a lower temperature. What happens to the temperature of both the bodies?

• A. Temperature of A decreases
• B. Temperature of A increases
• C. Temperature of B decreases
• D. Temperature of B increases

Answer 1

The correct option is A

Temperature of A decreases

When two bodies are brought into contact, heat flows from one body to another till their temperatures are equal. Hence the temperature of the body which is at higher temperature decreases and the temperature of other one increases. So the temperature of body A decreases while that of B increases.
