Answer to Question #259781 in General Chemistry for Choi

Question

You have one mol sample of water at -30 °C and you heat it until you have gaseous water at

140°C. Calculate q for the entire process in kJ/mol .

Answer 1

You will need to know the specific heat capacity of ice to go from -30C to 0C; then the latent heat of ice/water to turn the ice into water, then the specific heat capacity of water to go from 0C to 100C, then the latent heat of water/steam to turn the water into steam, then the specific heat capacity of steam to go from 100C to 40C. 

Q=mcΔT

Q=728094.7
