Question

After the water has boiled, the temperature of the water decreases by 22 °C.

The mass of water in the kettle is 0.50 kg.
The specific heat capacity of water is 4200 J/kg °C.
Calculate the energy transferred to the surroundings from the
water.



Energy=

Answer 1

Step-by-step explanation:

Use the formula:

`e = mc \delta \theta`

e is the energy released,

m is the mass of water,

c is the specific heat capacity,

δθ is the change in temperature ( 100 - 22)
