1.00 mole of an ideal monoatomic gas at STP first undergoes isothermal expansion so that the volume at b is 2.5 times the volume
MrRa [10]

Answer:

the pressure at c = 0.27 atm

Explanation:

Given that:

number of moles (n) = 1.0 moles

Value of gamma in the monoatomic gas (γ) = 5/3

During an isothermal expansion, the volume at b is = 2.5 times the volume at a ; this implies that:

V_b = 2.5 V_a

∴ To calculate  the pressure at c from a; the process is adiabatic compression; so we apply:

P_aV_a^\gamma=P_cV_c^\gamma

\frac{P_c}{P_a}=[\frac{V_a}{V_c}]^{(2/3)

\frac{P_c}{1.0 atm}=[\frac{1}{2.5}]^{(2/3)

P_c=0.27 atm

Thus, the pressure at c = 0.27 atm

navik [9.2K]

Explanation:

A solution is said to saturated when it cannot dissolve any extra solute in it. The extra solute put remains undissolved.

A solution is said to unsaturated, when the concentration of solute is less as compared to solubility of the solution it is said to be unsaturated.

A solution is said to be super saturated when it contains more of the solute than the solvent  can dissolve under normal conditions is called super saturated.
