• Calculate the heat energy required to convert completely 10 kg of water at 50°C into steam at 100°C, given that the specific heat capacity of water is 4200 J/(kg°C) and the specific latent heat of vaporization of water
is 2260 kJ/kg.

We have,

We know that,

Heat required for temperature change in the same phase

Subsitute the required values,

Heat required for phase change at the same temperature

Subsitute the required values,

Therefore,

Total heat energy required to convert 10kg of water

Hence, The heat required to convert completely 10kg of water at 50° C into steam 100° C is 2.47 × 10^7 J/kg°C or 2.47 × 10^4 kJ/kg°C.

answer: i pick a

explanation:

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
