A0.780-kg silver pellet with a temperature of 85 oc is added to 0.150 kg of water in a copper cup of unknown mass. the initial temperature of the water and the copper cup is 14 oc. the equilibrium temperature of the system (silver+water+copper cup) is measured to be 29.5 °c. assume no heat is exchanged with the surroundings. the specific heats of silver, water and copper are: 234 j/(kg oc), 4186 j/(kg oc) and 387 j/(kg oc) , respectively. calculate the heat released by the correct choice in (a). keep 2 decimal places. report all heat as positive.

10859.94 j (already solved)

a. the above released heat is absorbed by the other two substances, assuming no heat is exchanged with the surroundings. calculate the heat absorbed by water.

b. the above released heat is absorbed by the other two substances, assuming no heat is exchanged with the surroundings. calculate the heat absorbed by water.
