I'm having a problem solving two problems, wondering if someone can help me out...(adsbygoogle = window.adsbygoogle || []).push({});

1)Blood can carry excess energy from the interior to the surface of the body, where the energy is dispersed in a number of ways. While a person is exercising, 0.645 kg of blood flows to the surface of the body and releases 1860 J of energy. The blood arriving at the surface has the temperature of the body interior, 37.3 °C. Assuming that blood has the same specific heat capacity as water, determine the temperature in degrees Celsius of the blood that leaves the surface and returns to the interior.

I'm assuming that you would use the equation T=Q/cm and when I do, I end up with an answer of .95 degrees celcius which I know is wrong. Can anyone explain this to me?

2)When resting, a person has a metabolic rate of about 2.34 x 105 joules per hour. The person is submerged neck-deep into a tub containing 1.81 x 103 kg of water at 26.8 °C. If the heat from the person goes only into the water, find the water temperature in degrees Celsius after half an hour.

Not really sure what equation to use here. I'm thinking Q=cmT...am I right in thinking this?
