A weight lifter manages to lift a 147 kg weight a distance of 1.1 m. Treat her as a thermodynamic system and find how much heat (in kcal) she must put out if her internal energy decreases by 3620 J during the lift.

2. Relevant equations

delta U=Q-W

3. The attempt at a solution

-3620= Q-(9.8*147*1.1)

Q=-2035.34

I was wondering wut the units of Q are? if it's in joules how do i convert to kcal?

Thanks in advance!
