Question

If you heat a fixed quantity of gas, which of the following statements are true?Check all that apply.a.The volume will always increase.b.If the pressure is held constant, the volume will increase.c.The product of volume and pressure will increase.d.The density of the gas will increase.e.The quantity of gas will increase.

Answer 1

Step-by-step explanation:

Given

there is fix Quantity of gas i.e. mass of gas is constant

From ideal gas Equation

PV=nRT

(a) volume always increases is not true as Pressure can also be increased .

(b)If Pressure is constant along with mass then as Temperature increases, Volume also increases.

(c)true , Product of Pressure and volume depends upon temperature thus it also increases with temperature.

(d)Density of gas may or may not increases

As density is
`(mass)/(volume)`

volume may increase or decrease as temperature increase .

(e)false

as it clearly stated that quantity of fixed therefore there is no change in gas
