- Responses should be as simple as possible, and in typed form, with all applicable units, following a clear and straightforward logical structure. NO hand-drawn explanations are allowed. Ensure the appropriate use of significant figures, and when applicable, employ the "variable space" framework for providing answers.Part A A large cavity that has a very small hole and is maintained at a temperature T is a good approximation to an ideal radiator or blackbody. Radiation can pass into or out of the cavity only through the hole. The cavity is a perfect absorber, since any radiation incident on the hole becomes trapped inside the cavity. Such a cavity at 400 has a hole with area 5.00 mm². How long does it take for the cavity to radiate 100 J of energy through the hole?

- Consider the two-sided chamber shown, where the right side has a volume of V and the left side has a volume of 2V. The chamber has a seal which separates the right from the left half. The chamber is sealed and an ideal gas is pumped into the right side at a pressure P and temperature T. The seal between the two sides is then opened. a If the temperature in the chamber is decreased by a factor of 2 by a refrigeration system while the gas fills the chamber, give an expression for the new pressure P' in terms of the original pressure P. b) The chamber is then sealed again, trapping 2/3 of the gas molecules in the left side. The temperature of the left side is then doubled by a heater, back to the original temperature T. What is the pressure in the left side of the chamber now, in terms of the original pressure?An ideal gas is confined to a container at a temperature of 360 K. 1) What is the average kinetic energy of an atom of the gas?

This problem compares the heat input to your skin from steam as opposed to hot water at the same temperature. How much heat Q1 is transferred by 25.0 g of water onto the skin? To compare this to the result in the previous part, continue to assume that the skin temperature does not change. Assume that water and steam, initially at 100° C, are cooled down to skin temperature, 34° C, when they come in contact with your skin. Assume that the steam condenses extremely fast.
