A sample of 3.44 mol of krypton is confined at low pressure in a volume at a temperature of 86 °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 -32 °C. (b) The volume is quadrupled. (c) The amount of krypton is increased to 4.75 mol. Give each answer as a decimal factor of the form: new value = factor old value. A factor of 1 means no change. Change KE avg urms
