What is 50 C in Kelvin?

There are 65 liters of helium in a balloon at 35 K. If the temperature of the balloon is increased to 40 K, what will the new volume of the balloon be? Include units and round to the nearest tenth.

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 0.6 L and a temperature of 20°C, what will the volume of the balloon be when it heats up to a temperature of 176°C? Include units and round to the nearest tenth.

Edelman and Gronkowski want to play a game of beach volleyball. If the beach ball has a volume of  261 L at a temperature of 502 K, what will the temperature (in Celsius) of the balloon be if the volume decreases to 176 L? Include units and round to the nearest whole number.

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be ... (Include units and round to the nearest whole number.)

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 in Kelvin?

• 0 K
• 546 K
• 273 K
• 100 K

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? Include units and round to the nearest tenth.

Convert: 253 °C to K:

100 °C = _____ K

Convert: 175 K to °C:
