One litre of a gas weights 28 at 300 K and latm pressure. If the pressure is made 0.75 atm, at what temperature will one litre of the same gas weigh lg 

A

600K

B

800K

C

900K

D

450K

Text Solution

Verified by Experts

The correct Answer is:
D
`(P_1V_1)/(W_1T_1) = (P_2V_2)/(W_2T_2) 1/(2 xx 300) = (0.78)/(1 xxT_2) implies T_2 = 450 K`.
