1)two rigid tanks of equal size and shape are filled with different gases. the tank on the left contains oxygen, and the tank on the right contains hydrogen. assume both gases are ideal. the molar masses of oxygen and hydrogen are 32 and 2, respectively. both containers are at the same temperature. a pressure gauge is pin oxygen hydrogen connected to each tank. both gauges show a reading of 230 kpa.
is the number of oxygen molecules in the left container greater than, less than, or equal to the number of hydrogen molecules in the right container? explain your reasoning.
2) a cylindrical pump contains one mole of an ideal gas. the piston is free to move, but no gas can enter or leave the pump. neglect friction between the piston and the cylinder walls.
the piston is quickly pressed inward as shown in the diagram. a sensor in the pump records an increase in temperature.
a. how can you account for the increase in temperature of the gas? explain.
b. did the thermal energy of the gas increase, decrease, or remain the same in this process? explain.

As seen in a us weather map, the h (or high) and l (or low) symbols indicate regions where surface air pressures are high or low, respectively, compared to surrounding areas. an h is plotted where the air pressure is highest and an l is plotted where the air pressure is lowest. proceeding outward and away from the center of a high pressure system, the air pressure "
