1) The Volume of 10 mols of a gas at a pressure of
atm is 200 L(liters). What is its temperature in kelvin to the nearest degree?
2) What is the pressure to the nearest N/m^2 of 2 mols of a Gas with a volume of 540 L(liters) and a temperature of
kelvin?
3) A gas bubble with an initial volume of 7 milliliters rises from a depth of
meters.If the temperature does not change, what is its volume to the nearest ml when it reaches the surface(density of water=1000 kg/m^3)?
4) If the temperature in Celsius is
, what is the temperature(to the nearest degree) in kelvin?
