Answer: Option (b) is the correct answer.
Explanation:
According to the law of conservation of energy, it is known that energy can neither be created nor it can be destroyed.
But energy can be changed from one form to another.
Whereas entropy is the degree of randomness present within the molecules of a substance or object.
For example, gas molecules are able to move rapidly so, they have more entropy as compared to solid and liquid substances.
According to second law of thermodynamics, entropy of the system is always increasing.
Thus, we can conclude that "Conservation of energy" refers to the fact that energy cannot be created or destroyed but can be converted from one form to another.

Answer:
V₂ = 2.0 Liters at STP conditions
Explanation:
Solving problem using the combined gas law
Given:
Case I Conditions Cast II Conditions
P₁ = 825mmHg P₂ = 760mm
V₁ = 2.30 Liters V₂ = ?
T₁ = 70°C + 273 = 343K T₂ = 0°C = 273K
Substitute into combined gas law assuming moles of gas remains constant; solve for unknown volume under case 2 conditions
P₁·V₁/n₁·T₁ = P₂·V₂/n₂T₂ => V₂ = P₁·V₁·T₂ / P₂·T₁ => note: in this solution, moles of gas remains constant as is disregarded in final calculation.
V₂ = (825mm)(2.3L)(273K) / (760mm)(343K) = 1.987 Liters (calculator answer) ≅ 1.9 Liters (2 sig figs based on given volume (V₁)
V₂ = 1.987 Liters ≅ 2.0 Liters (2 sig figs based on given volume (V₁)
