Question

A scientist fills a balloon with a gas at 200 degrees Kelvin. The volume of the balloon is 150 cm3. Then, the scientist places the balloon in a freezer and the temperature drops to 100 degrees Kelvin. What will be the volume of the balloon? Show work! 

Answer 1

Temperature 200K = 100K

Volume 150 cm³ X

Cross Multiply: 200 x X --> 200Kx 150 cm³ x 200 -> 15000cm³

Solve: 200x = 15000 (Divide both sides by 200

200 200

x = 75cm³

The volume at 100K is 75cm³
