# Question

A 1.00-mole sample of an ideal gas in a vessel with a movable piston initially occupies a volume of 5.00 L at an external pressure of 5.00 atm.

a. If Pex is suddenly lowered to 2.00 atm and the gas is allowed to expand isothermally, calculate the following quantities for the system: ΔE, ΔH, ΔS, ΔG, w, and q.

b. Show by the second law that this process will occur spontaneously.

One mole of an ideal gas with a volume of 6.67 L and a pressure of 1.50 atm is contained in a vessel with a movable piston. The external pressure is suddenly increased to 5.00 atm and the gas is compressed isothermally (T = ...You have a 1.00- L sample of hot water (90oC) sitting open in a 25oC room. Eventually the water cools to 25oC, whereas the temperature of the room remains unchanged. Calculate ΔSuniv for this process. Assume the density of ...Consider 1.00 mole of an ideal gas at 25oC. a. Calculate q, w, ΔE, ΔS, ΔH, and ΔG for the expansion of this gas isothermally and irreversibly from 2.45 × 10-2 atm to 2.45 × 10-3 atm in one step. b. Calculate q, w, ΔE, ...Define the following. a. Spontaneous process b. Entropy c. Positional probability d. System e. Surroundings f. Universe When a person exercises, muscle contractions produce lactic acid.
