Question

Describe the process that ice on Mount Everest goes through when being heated from 10o Fahrenheit to 305o Kelvin. Explain how the energy requirements change at different steps of the heating curve. What are the energy transfers that happen in the ice on Mount Everest?

Answer 1

Melting point of water is 32F or 273.15 K
Boiling point of water is 212 F = 373.15 K

First ice is warmed from 10F to 32 F
Heat capacity of ice is 2.09 kJ/kg K
Then ice melts, during this temperature remains same.
For melting, energy is 333 kJ / kg K
Water warms to 305 K.
Heat capacity of water is 4.19 kJ / kg K
