Question

US Question 10 4 points Save Answer and The figure shows a pV diagram for 43 g of oxygen gas (O2) in a sealed container. The temperature of the gas in state1s 21°C What are the temperatures 4 of the gas in states and 4? The ideal gas constant is R = 3314 mol K-00821L tr/mol K and the ATOMIC weight of oxygen is 16 gimol 16'C 47°C 52 C 350 C 11' 32"C 220'C 660°C

Answer 1

According to Ideal gas eqr, PV = nRT To -0 T = 421 c = 294K 10r (+273) k) in state to i P, (100) ? = 294 - - DR [nr = constant, . We need not to calculate it as we can calculate the temperatures to by taking ratios] for state 3, P= 1,58, , V = 50 :- (1.5P,)(50) - Tz NR taking ratio of ② & ③,

147 ::T=294x 1.5.xsd toor = 220.5 K =(220.5-273)ºs = -52.5°C 9-52°c [option (b) is correct - we can also check for state 4. p=1.58,, v= 150 .: (1.5)P, (150) - NR .. taking ratio of 6 & 6 and re-arranging, er han 5Y503 toor = 661.5K = 388.5C = 390°C We can also find value of n If you require no weight nam " molecular weight 20.26875 mol = ku 4.33 16 g/mol

option b is correct.
