If a hairspray can is heated, what can be expected of the pressure of the gas inside the can?
The pressure will increase
The pressure will decrease
The pressure will remain constant
The pressure will equalize
Pressure is
defined as the mass that an object exerts when at rest.
not a measurable in gases.
defined as the number of moles of substance divided by the mass of the substance.
created by the force of the gas particles impacting the walls of the container.
Absolute zero is
0 K
where there is no molecular movement
the coldest temperature possible
all of these
A student inflates a balloon with helium then places it in the freezer. The student should expect
the balloon's volume to increase
the balloon's volume to decrease
the balloon's moles to increase
the balloon's moles to decrease
The pressure of a 6.5 L sample of oxygen gas is measured to be 3.8 atm. If the gas is transferred into a 12 L tank, what is the new pressure?
6.6 atm
3.9 atm
4.5 atm
2.1 atm
When a piston compresses in a chamber the volume of the gas inside decreases. What happens to the pressure and which gas law is this representing?
