Question

The temperature of a sample of fluorine gas is changed without changing its volume, causing a change in pressure from 46.0 kPa to 129.0 kPa. If the starting temperature was 225 °C, what is the final temperature in degrees Celsius?

Answer value

Answer 1

P₁= 46.0kPa

T₁ = 225+273 = 498 k

P₂=129.0kPa

P₁ / T₁ = P₂ / T₂

$\frac{46}{498}= \frac {129}{T2}$

$T2= \frac{498×129}{46}=1396.57$

T₂ in degrees celsius= (1396.57 - 273) = 1123.57 degrees Celsius
