q represents the change in heat of a reaction or substance. The units of q are Joules (J) or kilojoules (kJ). For a well understood substance, we can calculate the specific heat which relates the mass of the substance in grams to the amount of heat in J required to raise that amount a certain temperature. We call that specific heat. The specific heat (Cs) of water is stated in the following way: C s ( H 2 O ) = 4.186 J g ∘ C This means that it takes 4.186 J of energy to raise the temperature of 1g of water by 1ºC. The relationship between q and Cs for a given substance is where m is mass (g) and ∆T is the change in temperature in ºC (final temp - initial temp). Calculate the heat change (q) in J when 4.297 grams of water is cooled from 3.967 ºC to -2.902 ºC. Enter your answer with one decimal place (tenths). Pay careful attention to the sign of your answer. The sign of ∆T is always the same as the sign for q.
