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

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 gas at 25^ο C is 3.8 L.  What will be the volume of that gas at 57 ^ο C if the pressure is held constant?

• 8.66 L
• 4.21 L
• 6.34 L
• 3.46 L

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

The pressure remains constant over a sample of neon gas occupying a volume of 255 mL . The volume is now 323mL because the temperature has increased to 369 K. What is the original temperature of the gas?

• 291 K

• 223 K

• 467 K

• 76 K

A sample of argon gas is at a temperature of 20 °C. The temperature is increased to 30°C so that the volume is now 373 mL. What was the original volume?

• 361 mL

• 411 mL

• 254 mL

• 249 mL

When the temperature of a gas decreases (with pressure and amount held constant), does the volume increase or decrease?

• Unaltered

• Remains constant

• Increase

• Decrease

Charles' Law deals with what quantities?

• pressure/temperature

• pressure/volume

• volume/temperature

• volume/temperature/pressure

Tom Brady enjoys balloon animals from the carnival. He just received a balloon giraffe that has an initial temperature of 39.0°C and a volume of 1.28 L. If Gronkowski plays a trick on Tom, and puts his balloon giraffe into the freezer, what would be the new volume of the balloon if the temperature drops down to 8.0°C?
(Don’t forget about what must be done to temperatures!)

• 1.42 L
• 6.85 x 10⁴ L
• 3.78 L
• 1.15 L
