Water at the Antarctica usually exits as ice, making it very difficult to use the water or conduct experiment requiring the water to be in liquid state. A coffee addicted physicist stationed at a research base requires about 0.8 kg of ice for his coffee on the hour. a. How much heat is required to convert 0.8 kg of ice at —35 °C into steam at 100°C?

Explanation:
Water turns into ice when temperature decreases to 0°C. Water turns into steam at 100°C when heat is supplied to water. Water as steam has more latent heat while water as liquid does not.
Hence, water as steam may cause severe burns while water as ice has a During liquification of ice to water, an equilibrium is established. The rates of transfer of molecule from ice to water and from water to ice will remain same at the given temperature and atmosphere pressure, so, the mass of ice and water do not change. But, the system is in the state of dynamic equilibrium.
