A 0.500-mole sample of a gas has a volume of 11.2 liters at 273K. What is the pressure of the gas

1.00atm

At what condition of temperature and pressure would the molecules of a gas have the greatest average kinetic energy?

100°C and 1 atm

Under what conditions does a real gas behave most like an ideal gas?

A high temp and low press

An ideal gas is made up of gas particles that

Are in random motion

A flask containing molecules of gas and a separate flask containing the molecules of gas b are both at the same temperature. Gases a and B must have equal

Average kinetic energy's

As the pressure on a sample of a gas increases at constant temp, the volume of the gas

Decreases

The volume of a sample of hydrogen gas at STP is 1.00 liter. As a temperature decreases, pressure remaining constant, the volume of the sample

Decreases

The volume of a given mass of an ideal gas at constant pressure is

Directly proportional to the Kelvin temp

The volume of a given mass of an ideal gas constant pressure is

Directly proportional to the Kelvin temperature

According to the kinetic theory of gases which assumption is correct

Energy may be transferred between colliding particles

According to the kinetic theory of gases, which assumption is correct?

Energy may be transferred between colliding particles

One reason that a real gas deviates from an ideal gas is that the molecules of the real gas have

Forces of attraction for each other

Which gas will most closely resemble an ideal gas at STP

H2

which gas under high pressure and low temperature has a behavior closest to that of an ideal gas

H2(g)

A sample of gas A in a container at a temperature of 50°c and a pressure of 0.50 atmosphere. Compared to a sample of gas B at STP, gas A had a

Higher temp and a lower press

If the pressure on a given mass of a gas in a closed system is decreased and the temp remains constant, the volume of the gas will

Increase

If the pressure on a given mass of gas in a closed system is decreases and the temp remains constant, the volume of the gas will

Increase

If the pressure on a given mass of gas in a closest them is decreased in the temperature remains constant volume of the gas will

Increase

A 100.-milliliter sample of helium gas is placed in a sealed container of fixed volume. As the temp of the confined gas increases from 10°c to 30°c, the internal pressure

Increases

A sample of gas is at STP. As the pressure decreases and the temp increases, the volume of the gas

Increases

As the space between molecules in a gas sample decreases the tendency for the behavior of this gas to deviate from the ideal gas law's

Increases

When a sample of a gas is heated at constant pressure, The average kinetic energy of its molecules

Increases, and the volume of the gas increases

An assumption of the kinetic theory of gases is that the particles of a gas have

Little attraction for each other and an insignificant volume

A real gas would behave most like an ideal gas under conditions of

Low pressure and high temperature

A real gas would behave most like an ideal gas under conditions of

Low pressure, high temp

Equal volumes of all gases at the same temp and pressure contain an equal # of

Molecules

The volume of a 1.00-mole sample of an ideal gas will decrease when the

Pressure increases and the temp decreases

The volume of a 1.00-mole sample of an ideal gas will decreases when the

Pressure increases and the temp decreases

As a given volume of gas is compressed, the # of molecules

Remains the same

As the pressure on a given sample of a gas increases at constant temp, the mass of the sample

Remains the same

As the pressure on a given sample of a gas increases at constant temperature, the mass of the sample

Remains the same

Real gas behavior deviates from ideal gas behavior BC real gas particles have

Volume and some attraction for each other

Real gas behavior deviates from ideal gas behavior because real gas particles have

Volume and some attraction for each other

The average kinetic energy of the molecules of an ideal gas is directly proportional to the

Volume occupied by individual gas molecules

Which gas is least likely to obey the ideal gas law is very high pressures and very low temperatures
