If the pressure is initially 1.30 atm before the addition of the gas and the position of the piston does not change, what is the new pressure inside of the cylinder?

The new pressure inside of the cylinder is 2.6 atm.

Explanation:

Given that,

Initial pressure = 1.30 atm

If the number of moles is double after gas added.

The position of the piston does not change.

So, The volume will be same.

The pressure inside the cylinder before gas added

...(II)

After gas added,

...(II)

We need to calculate the new pressure inside of the cylinder

Dividing equation (I) and (II)

Put the value into the formula

Hence, The new pressure inside of the cylinder is 2.6 atm.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
