Boyle's and Charles' Law

A sample of oxygen gas occupies a volume of 250.mL at 740. torr pressure. What volume will it occupy at 800. torr pressure?

• 266 ML

• 245 ML

• 231 ML

• 217 ML

A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure. What pressure would the gas exert if the volume was decreased to 2.00 liters?

• 219 KPa

• 222 KPa

• 567 KPa

• 654 KPa

If I have 5.6 liters of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be?

• 6.3 ATM

• 2.4 ATM

• 1.8 ATM

• 8.6 ATM

A gas with a volume of 400 mL at 120 ^οC is heated until its volume is 700 mL.  What is the new temperature ( in degree Celsius) of the gas if the pressure is constant?

• 4 14.75 ^οC

• 687.75 ^οC

• 210 ^οC

• 68.57 ^οC

A sample of oxygen gas in a closed system has a volume of 200 milliliters at 600 K. If the pressure is held constant and the temperature is lowered to 300 K, the new volume of the gas will be -

• 400 milliliters.

• 300 milliliters.

• 100 milliliters.

• 200 milliliters.

The volume of a sample of a gas at 273 ^oC is 200 liters. If the volume is decreased to 100 liters at constant pressure, what will be the new temperature of the gas?

• 0 K

• 546 K

• 273 K

• 100 K

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL

• 204 mL

• 196 mL

• 160 mL

Boyles Law Is A

• Directly Proportional Relationship

• Inversely Proportional Relationships

Boyles Law Tells That

• The More The Volume The Less The Temperature

• The More The Temperature The Less The Pressure

• The More The Volume The More The Pressure

• The More The Pressure The Less The Volume

What type of relationship to pressure and volume have?

• direct

• no relationship

• inverse

• I don't know
