Answer:
232.92K
Explanation:
The initial temperature of the argon is 232.9K.Calculation of the initial temperature:Since V₁ = 5dm³P₁ = 0.92atmT₂ = 30°CV₂ = 5.7LP₂ = 800mmHgHere we have to applied the gas lawP1V1/T1 = P2V2/T2Here p, v, and T are pressure, volume and temperature respetivelyAnd, 1 and 2 depict the initial and final states.Now we need to converttemperature to K and pressure into atmSo, it be like T₂ = 30°C = 273 + 30 = 303KP₂ = 800mmHg; 760mmHg = 1 atmSo, = 800/760 = 1.05 atmNow0.92*5 /T = 1.05*5.7/303So, the temperature is 232.92K
