Answer: 3. H2O(l) -> H2O(g)
Explanation: Entropy is a measure of the randomness or disorder a substance. Gasses have the greatest amount of entropy and solids have the least amount of entropy. The entropy of a sample of H2O increases as liquid water evaporates and changes to a gas.
Answer:
Hence volume of oxygen gas measured at 0oC and 1atm, ineeded to burn completely 1L of propane gas (C3H8) under the same conditions is 5L.

<span>Answer is:
the final temperature was 915 K.
p₁ = 1 atm.
T₁ = 305 K.
V₁ = 16 cm³
p₂ = 48 atm.
V₂ = 1 cm³.
T₂ = ?
Ideal law gas:
p₁V₁ / T₁ = p₂V₂ / T₂.
1 atm · 16 cm³ / 305 K = 48 atm · 1 cm³ / T₂.
T₂ = 305 K · 48 atm·cm³ ÷ 16 atm·cm³.
T₂ = 915 K.
p - pressure.of fuel air
T - temperature of fuel air.
V - volume of fuel air.</span>
Answer:
Negative
Explanation:
For a solution to form, the change in Gibbs free energy must be negative for dissolving. When a solute dissolves in a saturated solution, ΔH(enthalpy change) is negative and ΔS(entropy change) is positive, giving rise to a large negative ΔG(change in gibbs free energy) and a very high solubility.
