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

2.35 L

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

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
