Gas Laws and KMT

According to the kinetic molecular theory, which statement describes the particles in a sample of an ideal gas?

• The particles have attractive forces between them.

• The particles are considered to have negligible volume.

• The particles are constantly moving in circular paths.

• The particles collide, decreasing the total energy of the system.

A cylinder with a tightly fitted piston is shown in the diagram above. As the piston moves downward, the number of molecules of air in the cylinder

• decreases

• increases 

• remains the same

Which graph shows the relationship between pressure and Kelvin temperature for an ideal gas at constant volume?

• 
• 
• 
• 

A sample of chlorine gas is a 300 K and 1.0 atm. At which temperature and pressure would the sample behave most like an ideal gas?

• 0 K and 1.0 atm

• 150 K and 0.50 atm

• 273 K and 1.0 atm

• 600 K and 0.50 atm

As the temperature of a gas increases with the volume remaining constant, the pressure of the gas

• decreases

• increases

• remains the same

As volume of the gas in this container increases, pressure will

• decrease.

• remain the same.

• increase.

• I don’t know

If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?

• The pressure will increase

• The pressure will decrease

• The pressure will remain constant

• The pressure will equalize

Which statement must be true of an ideal gas?

• Gas particles are elastic and do not attract each other.

• The kinetic energy of gas is dependent on temperature

• Energy is not lost when gas particles collide with each other or with the walls of the container.

• All of the above

What are the values of STP (Standard Temperature and Pressure) ?

• 0 K and 1 atm

• 0 K and 760 kPa

• 273 K and 1 atm

• 0^°C and 760 atm

How does a real gas deviate from ideal behavior?

• Real gas particles have volume and travel in a circular path

• Real gas particles attract each other and travel in a circular path

• Real gas particles have volume and attract each other

• Real gas particles collide with each other and all have the same kinetic energy
