cold water

mass of calimeter+ water: 68.66g

mass of calimeter: 19.19g

mass of water: 49.47g

final temperature of water: 39.1C

initial temperature of water: 25.5C

delta(T) of water: 13.6C

hot water

mass of calimeter+ water: 79.55g

mass of calimeter: 20.61g

mass of water: 58.94g

final temperature of water: 39.1C

initial temperature of water: 52.2C

delta(T) of water: -13.1C

calulate the q-hotwater (specific heat of water 4.18J g^-1 C^-1)

calculate the q-coldwater

can someone please explain to me how this question is done? thanks =]
