Question

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?

Answer 1

Final volume is 3.50L

Step-by-step explanation:

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

`(P_1V_1)/(T_1) =(P_2V_2)/(T_2)`

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:

`(250kPa*1.75L)/(700K) =(53.2kPa*V_2)/(298K)`

0.625L = 0.1785*V₂

3.50L = V₂

Thus, final volume is 3.50L
