Which step will decrease the pressure of a gas inside a dosed autical container?
increasing the number of moles of gas
decreasing the volume of the container
increasing the speed of the gas partides
decreasing the temperature i

Decrease the temperature

Explanation:

An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure.

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

it's all four options.
