Question

An ideal gas is confined to a container with constant volume. The number of moles is constant. By what factor will the pressure change if the absolute temperature triples

Answer 1

1/3

Step-by-step explanation:

Gay Lusaac's law states that "the pressure of a given mass of gas is directly proportional with the absolute temperature of the gas, provided that the volume is kept constant."

In formula, we say that

P/T = k

Where

P = pressure at different points

T = temperature at different points

k = constant of proportionality

From the stated formula, if we multiply the temperature by 3, we have

P/3T = k

P * 1/3T = k

And from this, we see the pressure will change by a value of 1/3
