Question

A 346.9 ml sample of carbon dioxide was heated to 381 k. if the volume of the carbon dioxide sample at 381 k is 596.2 ml, what was its temperature at 346.9 ml?

Answer 1

The temperature at 346.9 ml is calculated using Charles law formula

that is V1/T1= V2/T2

T1= 381 K
V1= 596.2 ml
V2 = 346.9 ml
T2=?
by making T2 the subject of the formula T2= T1V2/V1

T2 = 381 x 346.9/596.2 = 221.69 K
