The internal energy of a substance:...

The internal energy of a substance:

A

Increases with increase in temperature

B

Decreases with increase in temperature

C

Remains constant

D

Calculated by `E=mc^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
The fixed quantity of any substance is associated with a definite amount of energy which depends upon chemical nature of the substance and its state of energy. This energy is called Internal energy or intrinic energy(`mu` ). It is a state function and increases with increase in temperature.
