Question

HEYA!!

Two gases are mixed at same temperature pressure and volume, if volume and temperature don't change what will be resultant pressure?

COPIED ANSWER REPORTED!

Answer 1

Well, the Pressure should increase.

Boyle's Law is valid only when two conditions are fulfilled:

• Temperature should be constant

• Number of moles of gas should be constant

Here the first condition is satisfied. But the second condition is not. So Boyle's Law cannot be directly used to determine the answer.

We can obtain our logic from the Ideal Gas Equation:

PV = nRT

Since V, T and R are constants according to the given question, here we have

"P" is directly proportional to "n"

On mixing gases, the total number of moles will obviously increase. So consequently, the pressure must increases.

Answer 2

the temperature should increase by using boyels law
