Please show full solution, please type it thankyou

1. A cast iron pipe is put in place when the temperature is 30C. How long will it be at 100 C if it is 100 feet long at 30 C? (Iron = 12x10^-6/C value in the table) (Coefficient of Linear Expansion)

2. How Many Calories must be supplied to heat 100 grams of cast iron from 30C to 100C ?

( iron = 0.11 cal/g C) (Heat capacities)

3. What amount of heat is needed to melt 50g. ice at Oc. (water = 80 cal/g) (heat of fusion.)

4. How much heat is needed to evaporate 400 g. of mercury that is already at its boiling point of the heat of vaporization (hf) of mercury is 71 cal/g
