20g of water is given 2090J of heat. Determine the change in the temperature of water.

Answers

Answered by MANOBALAN2305

When the temperature of a 20-gram sample of water is increased from 10 deg C to 30 deg C, the heat transferred to the water is obtained by multiplying the mass of water with heat capacity and the temperature change.

The heat capacity of water is 1 cal/g/deg C.

The temperature change is 30−10=20

The heat transferred to the water is 20×1×(30−10)=400 cal.
