Question

A gas at 127 celsius and 10.0 L expands to 20.0 L. What is the new

temperature in kelvin? (You must convert to Kelvin before calculating
this problem

Answer 1

800.3 Kelvin

Step-by-step explanation:

127°C = 400.15 Kelvin (because 127 + 273.15)

Charles Law:

`(V1)/(T1) = (V2)/(T2)` Thus,
`(10.0 L)/(400.15 K) = (20.0 L)/(T2)`

Then, work out the math algebraically.

T2 = 20.0 / (10.0/400.15)

= 20.0 / 0.02499...

= 800.3 Kelvin

This is assuming the pressure remains constant.
