A typical woman gives off heat at the rate of about 8,000 calories per hour. How long would a woman have to stay in a bath of 60L (60,000g) of 26oC water in order to raise the water temperature to 30oC. Presume that all the heat given off by the woman is transferred to the water, and that the water doesn't lose any heat to the air.
