Question

4 g of an ideal gas (vapour density = 20) is taken in a bulb of 10 dm3 volume, at a temperature of T K. The bulb is placed in a thermostat maintained at a temperature 125ºC more than the initial. To maintain original pressure, 0.8 g of gas has to be removed, then the value of T is​

Answer 1

Answer:

Explanation:

N1T1=N2T2

4×T÷40=3.2×(T+125)÷40

4T=3.2T+400

T=400÷0.8

T=500

As the Chang in temperature delta T is same in kelvin or in degree Celsius so I've directly taken T2=T+125
