Question:
I initially have a gas with a pressure of 84 kpa and aTemperature of 35 degree Celsius and I heat it to an additional 23degree Celsius . What will be the new pressure
Answer:
Assuming no volume, then,
P1/T1 = P2/T2
Where,
T1 = 35+273= 308 K
T2 = 35+23+273= 331 K
P1=84 Kpa
P2=?
Then,
or, 84/308 = P2/331
or, P2 = 84 x 331/308
or, P2= 27,804/308 = 90.27 kPa
Hence, the new pressure will be 90.27 kPa
