Question

a gas is filled in a cylinder its temperature increase by 20% and volume decrease by 20% if pressure remains constant what percentage of mass of the gas leaks out​

Answer 1

Answer:

20%

Explanation:

We are given that a  a gas filled in a cylinder its temperature increase by 20%.

Volume of gas in a cylinder decrease by 20%.

We have to find the percentage of mass of the gas leaks out.

We know that Density=$\frac{M}{V}$

$V=\frac{M}{D}$

Volume of gas is directly proportional to mass.If volume increases then the mass is also increases .When the volume decrease then the mass is also decrease.

We are given that volume decrease by 20% then the mass is also decrease by 20%.

Hence, the mass of the gas leaks out is 20%.

Answer 2

Answer: 33.33%

Explanation:

1. Used ideal gas law

2. Taking out Vfinal and T final

3. If gas comes out mole changes and Mole= given mass / Moler mass and moler mass is equal for same gas .

3. Equating

4. Percentage calculation initial - final / initial ×100 . And the answer is here .
