**Question:**The burner in a hot air balloon adds 6400 J of heat to the balloon while the balloon expands. As the balloon expands, it does 3100 J of work on the surrounding air. What is the internal change in thermal energy of the balloon?A. + 6400 J B. - 3300 J C. + 9500 J D. + 3300 J**Explanation:**This is a physics problem that deals with the First Law of Thermodynamics, which states that the change in internal energy (\(\Delta U\)) of a system is equal to the heat added to the system (\(Q\)) minus the work done by the system (\(W\)):\[\Delta U = Q - W\]In this scenario:- The heat added to the balloon, \(Q\), is 6400 J.- The work done by the balloon on the surrounding air, \(W\), is 3100 J.Using the formula:\[\Delta U = 6400\, \text{J} - 3100\, \text{J} = 3300\, \text{J}\]Therefore, the internal change in thermal energy of the balloon is \(+3300\, \text{J}\).The correct answer is D. + 3300 J.

The urban heat island effect is often strongest at night when temperatures would typically drop. What does this indicate about energy transfer and the material used in the building? (a) The material in buildings releases more energy at night than it absorbs during the day (b) The material in buildings absorbs a lot of energy during the day and when it gets colder at night the energy is released back into the cooler air. (c) The material in buildings absorbs energy during the day and releases it because the temperature of the buildings is lower than the cooler air (d) The material in buildings releases a lot of energy into the hot air during the day so at night all of the energy is still there
PROBLEM 4 A heat pump is used to meet the heating requirements of a house and maintain it at a comfortable temperature.
