Gas Laws Exam

What is 50 ^oC in Kelvin?

• 50 K

• 323 K

• 100 K

What will happen to the volume of a gas if the pressure increases, with constant temperature ?

• Increase

• Decrease

• Nothing

According to the Combined Gas Law, pressure and volume are inversely related which means that

• When pressure increases, volume increases

• When pressure decreases, volume decreases

• When pressure increases, volume decreases

If 6L of gas at 293K is compressed to 4L, what is the new temperature?

• 195 K

• 439.5 K

• 12.2 K

In order to convert to Kelvin, you add ______ to the Celsius measurement.

• 372

• 273

• 237

4L of a gas is contained at 300 kPa and 200K. What will its volume be in L at 140 kPa and 100K?

• 4.3L

• 6.2L

• 8.5L

If a balloon is cooled what will happen to the volume?

• Volume will increase

• Volume will decrease

• Volume will not change

When a cold tire is inflated to a certain pressure and then is warmed up due to friction with the road, the pressure increases. This happens because the

• air molecules hit the walls of the tire less frequently

• rubber in the tires reacts with oxygen in the atmosphere

• air molecules speed up and collide with the tire walls more often

If you place a balloon in a freezer what happens to the size of the balloon?

• stays still

• increases

• decreases

Gas Laws involve what three terms?

• Solid Liquid Gas

• Speed Velocity Acceleration

• Pressure Temperature Volume
