Heat and Thermodynamics question

2025 · 4 Apr · Shift 2 · Q64

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
There are two vessels filled with an ideal gas where volume of one is double the volume of other. The large vessel contains the gas at 8 kPa at 1000 K while the smaller vessel contains the gas at 7 kPa at 500 K . If the vessels are connected to each other by a thin tube allowing the gas to flow and the temperature of both vessels is maintained at 600 K , at steady state the pressure in the vessels will be (in kPa ).
