11. Liquid methane has a heat of vaporization of 122 calories per gram (cal/g). Compare the effectiveness of liquid methane and water for evaporative cooling.

Water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.

Explanation:

Since the heat of vaporization of water is 540 calories per gram and that of liquid methane is 122 calories per gram, for each gram of the water evaporated, 540 calories is lost while for each gram of liquid methane evaporated, 122 calories is lost.

Since a higher heat loss would result in a higher temperature drop, water is more effective for evaporative cooling than liquid methane since, it would result in a higher temperature drop for the same mass of liquid methane.

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
