500
Under these two conditions real gases tend to behave more like ideal gases.
What are low temperatures and very high pressures.
500
A gas sample is collected at 16 C and .982 atm. If the sample has a mass of 7.40 g and a volume of 3.96 liters, find the volume of gas at STP.
.164 L at STP.
500
If all gases under all conditions of temperature and pressure behaved liked an ideal gas, would liquids and solids exist, why or why not?
They would not exist because molecular interaction as the molecules would not exist as ideal gases never interact with one another meaning that they would never condense to form a liquid or solid. Additionally, ideal gases are in constant motion with elastic collisions meaning that they never lose kinetic energy which would be necessary for a solid or a liquid to form.
