A 2.0 L sample of dry air in a cylinder exerts a pressure of 3.0 atm at a temperature of 25 degrees Celsius. Without a change in temperature, a
piston is moved until the pressure in the cylinder is reduced to 2.0 atm.
What is the volume of the gas? Record your answer exactly like the given
volume of 2.0 L (2 digits) followed by a space then the unit using a capital
letter.

pls help due end of the day

Fill in the blanks for the following statements: the rms speed of the molecules in a sample of h2 gas at 300 k will be times larger than the rms speed of o2 molecules at the same temperature, and the ratio µrms (h2) / µrms (o2) with increasing temperature. a not enough information is given to answer this question b sixteen, will not change c four, will not change d four, will increase e sixteen, will decrease
