Answer:
180.87 °C
Explanation:
Applying pressure law,
P/T = P'/T'..................... Equation 1
Where P = Initial pressure of helium gas, T = Initial Temperature of helium gas, P' = Final Pressure of helium gas, T' = Final Temperature of helium gas
Make T' the subject of equation 1
T' = P'T/P......................... Equation 2
From the question,
Given: P = 1.5 atm, P' = 2.3 atm, T = 23°C = (23+273)K = 296 K
Substitute these values into equation 2
T' = (2.3×296/1.5)
T' = 680.8/1.5
T' = 453.87 K
T' = 453.87-273
T' = 180.87°C
