If the phase change is between liquid and gas the formula looks like q=mΔ vap and ΔH vap is called the heat of vaporization. For any given substance the ΔH vap is always bigger than the ΔH fus because the potential energy change is always larger when going from liquid to gas than from solid to liquid.
9) When a given quantity of water is heated at a constant rate, the phase change from liquid to gas takes longer than the phase change from solid to liquid because a. The heat of vaporization is greater than the heat of fusion b. The heat of fusion is greater than the heat of vaporization c.

The extra water is moved out of leaves through stomata (very tiny openings on leaves) as water vapor. Thus water enters the biosphere and exits into gaseous phase. Step 6: Runoff. As the water pours down (in whatever form), it leads to runoff. Runoff is the process where water runs over the surface of earth.

Calculate the specific heat capacity of a piece of wood if 1500.0 g of the wood absorbs 67,500 joules of heat, and its temperature changes from 32°C to 57°C. 4. 100.0 g of 4.0°C water is heated until its temperature is 37°C. If the specific heat of water is 4.18 J/g°C, calculate the amount of heat energy needed to cause this rise in ...
