5 A calorimeter contains 150 0 g of water at 25 1 C A block of copper metal is heated to 100 4 C by putting it in a beaker of boiling water The specific heat of copper metal is 0 385 J g C The copper is added to the calorimeter and after time the contents of the cup reach a constant temperature of 30 3 C What is the mass of the block of copper 6 Methane can be burned and the energy used to heat substances up a How much heat is required to heat 1 00 kg of water from 25 0 C to 90 0 C b Use available heats of formation to determine the change in enthalpy when methane is combusted you will need to write a balanced equation for this reaction
