2. If 1.75 L of a gas is at 700. K and is under 250. kPa of pressure, what will the new
volume be if the temperature is lowered to 298K and the pressure is brought down to
53.2 kilopascals?

Final volume is 3.50L

Explanation:

It is possible to find volume of a gas using combined gas law:

Where P is pressure, V is volume and T is temperature of 1: initial state and 2: final state

If initial state of the gas is:

1.75L of a gas is at 700K and is under 250kPa of pressure

And final state is:

298K and 53.2kPa.

Replacing:

0.625L = 0.1785*V₂

3.50L = V₂

Thus, final volume is 3.50L
