... The rate of heat that flows into the helium is P = (1)(5.67 × 10−8 )(1.1310)(77)4 = 2.2542 And the amount of heat lost from the helium is P = (1)(5.67 × 10−8 )(1.1310)(4.2)4 = 1.9954 × 10−5 Now, this is negligible compared to the heat flowing into the helium. In the time frame mentioned (one hour = ...
