Question

Heat capacity of ice: 2090 J kg^-1 degree C^-1 Heat capacity of water (liquid): 4186 J kg^-1 degree C^-1 Latent heat of fusion: 3.36 Times 10^5 J kg^-1 Latent heat of vaporization: 2.26 Times 10^7 J kg^-1 Give your answers to at least three significant figures. Your answers must be accurate to 1%. How much heat energy is required to raise the temperature of 602 g of ice from a temperature of-49 degree C to a temperature of-11 degree C? How much heat energy is required to raise the temperature of 602 g of water from a temperature of 59 degree C to a temperature of 83 degree C? How much heat energy is required to raise the temperature of 602 g of water (initially ice) from a temperature of-49 degree C to a temperature of 83 degree C? How much heat energy is required to evaporate 602 g of water which is initially at a temperature of 59 degree C?

Explanation / Answer

part 4 )

here first water will reach from 59 to 100 degree then it will change the phase

Q = mcdT + mLv

Q = 0.602 * 4186 ( 100 - 59) + 0.602 * 2.26 x 10^7

Q = 13708370.76 J

Q = 1.371 x 10^7 J
