what volune will be occupied by 0.578 L of gas at 273 K after its temperature is changed to 356 K at constant pressure/

V1/T1=V2/T2

V2=V1* T2/T1

V2= 0.443L

To find the volume of the gas at the new temperature, you can use the combined gas law equation:

(P1 * V1) / T1 = (P2 * V2) / T2

Where:
P1 = initial pressure (assumed constant)
V1 = initial volume
T1 = initial temperature
P2 = final pressure (assumed constant)
V2 = final volume (unknown)
T2 = final temperature

In this case, you are given:
V1 = 0.578 L
T1 = 273 K
T2 = 356 K

Since the pressure is assumed to be constant, we can remove the pressure terms from the equation:

(V1) / T1 = (V2) / T2

Now, let's rearrange the equation to solve for V2:

V2 = (V1 * T2) / T1

Substitute the given values into the equation:

V2 = (0.578 L * 356 K) / 273 K

V2 ≈ 0.751 L

Therefore, the volume occupied by the gas at 356 K at constant pressure will be approximately 0.751 L.
