Gas Pressure

As you go up to high altitudes, the Gas pressure decreases because _________

• The air in the high altitudes are is not compressed

• Because the amount of gas particles are decreasing

• Because the gas particles in high altitudes are less dense

• Because the gas particles are far away to the gravity

Why Mountain climbers takes oxygen tank with them ?

• Because there is less pressure

• Because there are less gas particles at high altitudes

• Because they cant breath properly

• All of the Above

In this Image the bottle was shrank because _________

• It has been heated

• It was cooled

• Less Gas Pressure

• The Gas particles had less energy

When the volume increases, the pressure

(a)  

What happens to the volume of the balloon if the temperature increased ?

• The volume will increase

• The volume will decrease

• There will be more energy

• There will be less gas pressure

What happen to the pressure if you in a gas if you compressed it in to a volume that was one-third the size ?

• The pressure will increase one- third because pressure and volume are inversely proportional

• The pressure will decrease by one-third of its original volume

• The pressure will increase three times

• The pressure will decrease three times

The pressure inside the syringe will decrease if we move the plunger in :

• Direction A

• Direction B

• We don't have to move the plunger as the pressure will change on its own.

• None of the above answers.

How can we increase the gas pressure inside a sealed container ?

• Increase the number of particles inside the container

• Increase the temperature

• Decrease the volume of the container

• All of these

Why the bicycle tyre does not expand like balloon ?

• Because the Balloon material is more elastic than bicycle tyre

• Because Bicycle tyre is heavier than Balloon

• Because the Bicycle tyre have more density than Balloon

• Because Bicycle tyre have more are and weight than Balloon

Pressure can be exerted by solids, liquids and gases.

• True

• False
