A Carnot engine is operated as an air conditioner to cool a house down in the summer. The air conditioning removes 14kj of the heat per second from the house, and maintain the inside temperature at 293k, while the outside temperature is 369k. The power required for the air conditioner under these operating conditions, in SI units, is closest to:

Oxygen and hydrogen gas are at the same temperature t. what is the ratio of kinetic energies of oxygen molecule and hydrogen molecule if oxygen is 16 times heavier than hydrogen.

Based on this activity, is kinetic energy always transformed into potential energy?

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a. water evaporates, which favors the formation of h2co3. b. pressure decreases, which favors the formation of h2co3. c. the open container warms up, which causes more gas to escape. d. co2is removed, which favors the formation of h2co3.
