How much heat (in joule) is required to raise the temperature of 205 g of water from 21.2^(@)C to 91.4^(@)C . Specific heate of water is 4.18 J g^(-1) .^(@)C^(-1) Strategy : The specific heat of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1^(@C . Thus Specific heat = (("Amount of heat in joules"))/(("Mass of substance in grams")("Temperature change in" .^(@)C)) Rearrangement gives. Amount of heat (q) = Mass of substance (m) xx Specific heat (c ) xx Temperature change (Delta T)
