Homework Statement
A cylinder of nitrogen is pressurised to 200 BAR at 25oC
The cylinder is left to cool outside on a winters day to –5oC
What is the pressure of the Nitrogen once it has cooled?
Homework Equations
P1/T1=P2/T2 ?
The Attempt at a Solution
25+273 = 298 Kelvin. 273-5=268 Kelvin.
200/298=0.6711409396
0.6711409396 x 268 = 179 BAR ?
Have i used the relevant equation? Going through some practice questions but cant find the solutions. doh.
cheers
