If a beach ball has a volume of 261 L at a temperature of 502 K, what will be the new temperature of the balloon if the volume decreases to 176 L? (a)   K

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? (a)   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? (a)   mL

The pressure remains constant over a sample of helium gas occupying a volume of 638 mL. The temperature is increased to 471 K and the volume is now 953 mL. What was the original temperature? (a)   K

(Charles Law) There are 70 liters of helium in a balloon at 18 K. If the temperature of the balloon is increased to 20 K, what will the new volume of the balloon be? (a)   L

(Charles Law) There are 68.0 liters of helium in a balloon at 147 K. If the temperature of the balloon is increased to 200 K, what will the new volume of the balloon be? (a)   L

Tom wants his balloon back to normal size so he decides to put it on a heating vent. If the balloon initially has a volume of 0.78 L and a temperature of 293 K, what will the volume of the balloon be when it heats up to a temperature of 176°C? (a)   L

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

• 250 L

• 1000 L

• 500 L

• 2000 L
