Question 1: How much heat would be required to heat 1 gram of pure liquid water from 10oC to 20oC?
-1 gram multiplied by 10 degrees in terms of calories
Question 2: How much heat would be required to heat 10 grams of pure liquid water from 20oC to 25oC?
-10 grams multiplied by 5 degrees in terms of calories
-50 calories
Question 3: How much heat would be required to melt 3 grams of pure water ice at 0oC and convert it to 3
grams of pure liquid water at 0oC?
-melting=3 grams times 80 calories=240 calories
Question 4: How much heat would be required to evaporate 2 grams of pure liquid water?
-2 grams multiplies by 540 calories=1,080 calories
Question 5: How much heat would be required to melt 3 grams of pure water ice originally at 0oC and raise its
temperature to 10oC?
-melting=3 grams multiplied by 80 calories=240 calories
-temperature raise=3 grams multiplied by 10 degrees in terms of calories=30
