A sample gasin a 575ml container at a pressure of 1.85 atm and a temperature of 125 C is transferred to a new contaoner with volume of 825ml. what is the new pressure in the atmpsphere if there is no change in temperature?.
What is the new pressure, on athmospheres, if the temperature is oncreases by 20 C?
confused how to solve this problem. kindly teach me or i just need the formula for the 2 questions.
thanks a lot.
God bless
+128731 I'm not well-versed in Physics, but I believe we're using this relationship:
P1 V1 / T1 = P2 V2 / T2 so we have
1.85 * 575 / 125 = P2 * 825 / 125 ....so
P2 = [1.85 * 575] / 825 ≈ 1.29 atm
This makes sense, as the size of the container increases, the pressure decreases
For the second part, we have
1.85 * 575 / 125 = P2 * 825 / 145 ....so
P2 = [ 1.85 * 575 * 145] / [125 *825] ≈ 1.50 atm
The temperature increases.....so does the pressure, given the same size container
