Question
1)Which of the following is false?
-The hotter the gas, the higher the pressure.
-The colder the gas, the lower the pressure.
-The more gas inside a container, the higher the pressure.
-The less gas inside a container, the higher the pressure.
2)Why doesn't atmospheric pressure crush a can?
-Because the volume of the can is always constant.
-There is no gas in the can.
-Because atmospheric pressure is too weak.
-The gas in the can is pushing back (against atmospheric pressure).
3)When you decrease the number of moles of a gas (let air out of a balloon) the volume _______________.
-increases
-decreases
-stays the same
Explanation / Answer
1)
P*V = n*R*T
-The hotter the gas, the higher the pressure.
If T is more, P will be more. Hence True
-The colder the gas, the lower the pressure.
If T is less, P will be less. Hence True
-The more gas inside a container, the higher the pressure.
if n is more, P will be more. Hence True
-The less gas inside a container, the higher the pressure.
if n is less, P will be less. Hence False
Answer:
-The less gas inside a container, the higher the pressure.
