Can someone help me solve these

1. A metal weighing 30 g absorbs 200.0 J of heat when its temperature increases by 80.0C. What is the specific heat capacity of the metal?2. Calculate the mass (in grams) of iron that could be warmed from 20C to 65C by applying 4.5 kJ of energy. The specific heat capacity of iron is 0.45 J/gC.3. How much heat in kilojoules is released when 500.0 g of water is cooled from 85.0C to 10.0C? The specific heat capacity of water is 4.184 J/(gC).4. If 2200 J of heat is absorbed by a sample of iron weighing 50.0 grams, how many degrees would its temperature change? The specific heat capacity of iron is 0.45 J/gC.5. The specific heat capacity of diamond is 0.509 J/gC, and 5000 J of energy is required to heat a 50 g sample of diamond to a final temperature of 98C. What was the sample's initial temperature?
