Answer:
Initial temperature of the gas cylinder was 167.7K
Explanation:
Based on Gay-Lussac's law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:
P1*T2 = P2*T1
<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
P1 = 1.25atm
T2 = 354.2K
P2 = 2.64atm
T1 = ?
1.25atm*354.2K = 2.64atm*T1
167.7K = T1
<h3>Initial temperature of the gas cylinder was 167.7K</h3>
