onsider a room with a slightly open window. A heater is turned on, raising the temperature of the air in the room. Since the room is open to the atmosphere, the pressure is constant. Take the air to be a calorically perfect ideal gas, so the specific energy can simply be written as u = cvT , where T is the absolute temperaturein the room. With these assumptions, how does the total energy in the room, U, change as the temperature is increased? What happens to the energy input by the heater into the room? A simple explanation is sufficient - no need to derive ananalytical result.

Determine the fraction of the magnitude of kinetic energy lost by a neutron (m1 = 1.01 u) when it collides head-on and elastically with a target particle at rest which is 21h (heavy hydrogen, m = 2.01 u).

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
