A)50 degree celsius
B)less than 20 degree celsius
C)between 20 degree celsius and 30 degree celsius
D)10 degree celsius
E)none of these

Answer 1

When one litre of water at 20 degree Celsius is mixed with one litre of water at 30 degree Celsius.

The temperature of the mixture will be in between 20 and 30 degree Celsius. This is because of the first law of thermodynamics.

Whenever two bodies at different temperatures are kept in contact the body at a higher temperature will start losing heat to the body at lower the temperature until both the temperature becomes equal.
