The heat of vaporization for dichlorodifluoromethane is 166 joules per gram (J/g) at he boring
point of -30°C. How much heat would be absorbed when 15 grams of liquid dichlorodifluoromethane
vaporizes at its boiling point?

2. how is heavy water different from normal water

3. how much energy in joules is required to evaporate .0005 kg of liquid ammonia to vapor at the same temperature? 4. how much energy ( in megajoules ) is given up by .75 kg of water at 0c when it freezes to form ice at 0c? 5. explain how heat works between and at critical temperatures?

What is the temperature of 0.750 mol of a gas stored in a 6,850 ml cylinder at 2.21 atm? . 2.95 k 5.24 k 138 k 246 k
