 $\frac{P_1}{T_1}\ =\ \frac{P_2}{T_2}$  

A gas has a pressure of 8 atm when the temperature is 400 K. The temperature drops to 200 K. Calculate the new pressure.

• 1 atm

• 2 atm

• 3 atm

• 4 atm

 $\frac{P_1}{T_1}=\ \frac{P_2}{T_2}$  

A gas has a pressure of 10 atm when the temperature is 100 K. The temperature increases to 300 K. Calculate the new pressure.

• 10 atm

• 20 atm

• 30 atm

• 40 atm

What type of relationship exists between volume and pressure?

• Direct

• Inverse

• There is no relationship

When exhaling, the size of lungs (volume) decreases.

How will the decreasing volume of the lungs affect the air pressure inside the lungs?

• it will decrease air pressure in the lungs

• it will increase air pressure in the lungs

• it will have no effect on air pressure

Rising up towards the water's surface decreases water pressure.

How will a decrease in water pressure affect the volume of gas bubbles?

• Decrease of pressure increases the volume of gas bubbles

• Decrease of pressure decreases the volume of gas bubbles

• Decrease of pressure has no effect on volume of gas bubbles

P₁V₁ = P₂V₂

A gas has a pressure of 6 atm and a volume of 5 liters. The volume changes to 10 liters. Calculate the new pressure.

• 1 atm
