A cylinder with a piston holds 3.50 moles of a diatomic gas. The gas in the cylinder absorbs 875 J of energy due to the higher temperature of the environment. At the same time, the cylinder expands to a larger volume, doing 112 J of work on the environment. (a) What is the change in internal energy of the gas in the cylinder (in J)

In a sample of oxygen gas at room temperature, the average kinetic energy of all the balls stays constant. which postulate of kinetic molecular theory best explains how this is possible? a. attractive forces between gas particles are negligible because the particles of an ideal gas are moving so quickly. b. collisions between gas particles are elastic; there is no net gain or loss of kinetic energy. c. gases consist of a large number of small particles, with a lot of space between the particles. d. gas particles are in constant, random motion, and higher kinetic energy means faster movement.

Put these processes of the water cycle in the correct order, starting at the point where the water is in the lake: 1. water evaporates into the atmosphere 2. rain, snow, or other precipitation falls 3. water collects into larger bodies of water 4. water vapor condenses into liquid water

What forms when chemical reactions combine pollution with sunlight?
