Question

10g of ice at-25degree Celsius is heated by a burner which is supplying heat energy at a rate of 250j/s heat gained by ice to attain temperature of zero degree Celsius is

Answer 1

Heat gained by ice to attain temperature of zero degree Celsius will be 500 Joules

Explanation :

The heat required to change the temperature of ice without changing its state is called specific heat and it is given by,

S = mcΔT

where,

m = mass of ice = 10 g

c = specific heat capacity of ice = 2 j/gC

ΔT = change in temp = 0 - (-25) = 25

Hence

S = 10 x 2 x 25 = 500 J

Hence heat gained by ice to attain temperature of zero degree Celsius will be 500 Joules
