Answer to Question #319982 in General Chemistry for low

Question

A 5.00 L of a gas is collected at 100. K and then allowed to expand to 20.0 L. What must the new temperature be in order to maintain the same pressure (as required by Charles' Law)?

Answer 1

Charles' Law:

V₁/T₁ = V₂/T₂

We have 3 of the 4 variables, and if we fill those in, we have...

5.00/100 = 20.0/T₂

Using the algebra skill of cross multiplying, we can get...

5.00T₂ = 2000

Dividing both sides by 5.00 to isolate the T₂, we get...

T₂ = 400k
