Think about a small helium tank the can fill 50 balloons. what must be true about the helium in the tank compared to the helium in the balloons?

compare charles' law to boyle's law. which one has a direct relationship, which one has an inverse or indirect relationship?

The pressure of the gas is higher in the tank, hence it can be compressed inside the tank.

Charle's Law:

The volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Boyle's Law:

The volume of the gas is inversely proportional to the pressure of the gas at constant temperature.

The helium can gas is compressed inside a tank by increasing pressure as stated by Boyles law.

When helium taken out of the tank into balloon its pressure will decrease hence, Volume will increase.

Therefore we can say that the pressure of the gas is higher in the tank, hence it can be compressed inside the tank.

petroleum? coal maybe?
