A human body loses about 360 kJ of heat every hour. Assuming that an average human body is equivalent to about 60 kg of water, what temperature decrease would this heat transfer cause?

the quation to use here is q=mc(delta T)

the variables are defined as follows

q= 360 kj

m= 60 kg

c= 4.19j/g degrees celsius (heat capacity of water)

delta T= unknown change in temperature

plug this all in to solve

q=mc(delta t)

360 kj = 60 kg x (4.19j/g degrees celsius) x (delta t)

1.4 degrees celsius = delta t

this heat transfer would cause a temperature decrease of aproximately 1.4 degrees celsius
