F.4 Ch. 4 Check Concept - Gas Laws & Kinetic Theory

The unit of pressure is Pa.

• True

• False

The pressure P of a fixed mass of gas is directly proportional to its volume V, provided that the temperature of the gas remains constant.

• True

• False

The volume of a fixed mass of gas is halved if the temperature in Kelvin scale is doubled, provided that the pressure of the gas remains constant.

• True

• False

We can determine the absolute zero temperature by extrapolating the P-T graph or V-T graph of a gas in Celsius scale.

• True

• False

The pressure of a fixed mass of gas will decrease if both the temperature and volume are doubled.

• True

• False

Brownian motion of smoke particles is caused by the bombardments between themselves.

• True

• False

The pressure in a container increases if the gas molecules inside bombard the wall of the container more frequently.

• True

• False

The space between gas molecules decreases when you compress the gas.

• True

• False

The average kinetic energy of the molecules of a gas is directly proportional to the absolute temperature of the gas.

• True

• False

Many gases obey the general gas law over a wide range of temperature and pressure.

• True

• False
