Gas Laws

The relationship of which two variables are compared in Boyle's Law?

• pressure & volume
• volume & temperature
• temperature & pressure
• volume & moles (amount of gas)

What happened to the volume between the two steps?

• volume increased
• volume decreased
• volume stayed the same

This graph is an example of two variables that are:

• directly proportional
• inversely proportional
• Straight line
• No relation

A gas occupies 4.98 L at 2.6 atm of pressure. What volume does it occupy at 1.8 atm pressure?

• 12.9 L
• 0.72 L
• 7.2 L
• 3.44 L

Which of the following temperatures is appropriate to convert 25^oC into the Kelvin scale?

• 373K

• 298K

• 372K

• 273K

A balloon with a volume of 200 mL at 30 ^οC is submerged in hot water to obtain a temperature of 50 ^οC.  What will happen to the volume of the balloon if the pressure remains the same?

• the volume of the balloon will become higher than 200 mL
• the volume of the balloon will become lower than 200 mL
• the volume of the balloon will stay the same
• there is no enough data

The pressure on a sample of gas is increased from 1.0 atm to 3.0 atm. If the new volume is 0.52 L, find the original volume.

• 0.52 L
• 1.56 L
• 0.173 L
• 1.00 L

Convert 5900 K to ^oC

• 6173 ^oC
• 5627 ^oC

Which of the following is not one of the postulates of the kinetic molecular theory for ideal gases?

• The particles attract and then repel each other.
• The collisions between particles are elastic
• The particles are in constant random motion.
• The particle size is very small compared to the space between the particles.
