Q = mc(delta theta) c = specific heat

seventy two-27=40 5 degree distinction 2500g H2O (4.184j/g) (40 5) (cancel grams, left with joules) = 470700 joules entire or 470.7 Kj (kilojoules). think of roughly it. you have 2500 g H2O, and it takes 4.184 joules to get a million gram of water a million degree warmer, so which you may desire to multiply the 2500g through four.184, then the 40 5 degree distinction in temperature. desire this facilitates!
