Question

How much heat is required to raise the temperature of 0.25 kg of water from 20°C to 30°C

Answer 1

10500 J/kg/*C

Step-by-step explanation:

Quantity of heat required=mass of substance x specific heat capacity x change in temperature

Quantity of heat required=0.25 x 4200 x [30-20]

Quantity of heat required=0.25 x 4200 x 10

Quantity of heat required=10500 J/kg/*C
