In a running event, a sprinter does 4.8 x 105 J of work and her internal energy decreases by 7.5 x 105 J. Determine the heat transferred between her body and surroundings during this event.
dq = du + dw
dq = -7.5 * 105 + 4.8 * 105
du = -ve sign show decrease internal energy
So,
dQ = -2.7 * 105J
So , amount of heat transfer between body and surroundings
Is dQ = 2.7 * 105J
plz upvote
