A box has a length of 45 centimeters, a width of 7 centimeters, and a height of 15 centimeters. What is the volume? A sample of water has a mass of 14 grams and a volume of 2 cubic centimeters? What is the density of water

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.
