A sample of 4.84 mol of neon is confined at low pressure in a volume at a temperature of 62 °C. Describe quantitatively the effects of each of the following changes on the pressure, the average kinetic energy per molecule in the gas, and the root-mean-square speed.

(a) The temperature is decreased to -55 °C.
(b) The volume is tripled.
(c) The amount of neon is increased to 5.92 mol.

Give each answer as a decimal factor of the form: new value = factor old value.   A factor of 1 means no change.

    A 1.72 mol sample of Kr gas is confined in a 40.4 liter container at 13.2 °C. If the amount of gas is decreased to 0.860 mol, holding the volume and temperature constant, the pressure will decrease because: Choose all that apply. As the number of molecule-wall collisions increases, the force per collision decreases. With fewer molecules per unit volume, the molecules hit the walls of the container less often. With lower average speeds, on average the molecules hit the...
