An ideal gas is placed in a container whose volume can be changed. Initially the gas has a volume of 0.05 m 3 and a pressure of 2.0 x 10 5 N/m 2 . The average kinetic energy of the atoms in the gas is 1.00 x 10 -20 J. 1) How many gas atoms are in the container? A 10-gram ice cube has been in a freezer at a temperature of -8.5°C for a long time.
