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

Answer 1

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.
