Question

A sample of a gas has a volume of 1.5L at 150K. If the gas is heated to 235K at constant pressure, what will its final volume be

Answer 1

The final volume of the gas when heated to 235K at constant pressure is 2.35L.

Step-by-step explanation:

In order to determine the final volume of the gas, we can use Charles's Law, which states that at constant pressure, the volume of a gas is directly proportional to its temperature. Mathematically, this can be represented as:

V1/T1 = V2/T2

where V1 and T1 represent the initial volume and temperature, and V2 and T2 represent the final volume and temperature.

Using the given information, we can substitute the values into the equation:

1.5L/150K = V2/235K

Solving for V2, the final volume, we find that V2 = 2.35L.

Answer 2

2.35 L

Step-by-step explanation:

From Charles Law

Applying,

V/T = V'/T'................. Equation 1

Where V = Initial volume of the gas, V' = Final volume of the gas, T = Initial Temperature of the gas, T' = Final temperature of the gas.

Make V' the subject of the equation

V' = VT'/T............... Equation 2

From the question,

Given: V = 1.5 L, T = 150 K, T' = 235 K,

Substitute these values into equation 2

V' = (1.5×235)/150

V' = 2.35 L

Hence the final volume of the gas is 2.35 L
