(Charles Law) The volume of gas in a balloon is 1.90 L at 21.0 ^oC. The balloon is heated, causing it to expand to a volume of 5.70 L. What is the new temperature of the gas inside the balloon?

• 7.00 C

• 63.0 C

• 120. C

• 609. C

(Charles Law) 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.

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter
