Your radiator on your car is normally 1.57 atm of pressure at 50.0 degrees Celsius. What does the pressure change to if the temperature increases to 128 degrees Celsius? Give an answer and an explanation on how you arrived at it.Radiator on your car is normally 1.57 atm of pressure at 50.0 degrees Celsius. What does the pressure ch?For an ideal gas the equation is pV=nRT
T is in deegres absolute.
So 50掳C=323K and 128掳C=401 K
We can write
p1V =nRT1
p2V=nRT2
Since V,n and R are the same
p1/p2=T1/T2
1.57/p2= 323 / 401
1.57/ p2 = 0.805
p2=1.57 /0.805= 1.95 atm
