Suppose 4 G of Water at 100°C Is Spread Over

question 52

Multiple Choice

Suppose 4 g of water at 100°C is spread over a large surface so that 1 g evaporates rapidly. If evaporation of the 1 gram takes 2,259 joules from the remaining 3 g of water and no other heat transfer takes place, what are the temperature and phase of the remaining 3 g once the 1 gram is completely evaporated?

• A)The remaining 3 g will turn to 10°C , liquid.
• B)The remaining 3 g will turn to 20°C liquid.
• C)The remaining 3 g will turn to -10°C ice.
• D)The remaining 3 g will turn to 0°C ice.
