Question

The third law of thermodynamics states that:, the entropy of a perfectly crystalline pure substance at zero $ \mathrm{K} $ is zero., absolute entropy of hydrogen ion is zero at zero $ \mathrm{K} $., Net change in entropy in conversionH $ _{2(\mathrm{~g})}(130 \mathrm{~K}) \rightarrow \mathrm{H}_{2(\mathrm{~g})}(200 \mathrm{~K}) $ is zero., entropy generally decrease in combustion reactions.

MARKS App · Accepted Answer

The third law of thermodynamics states that the entropy of a system approaches a constant value as the temperature approaches absolute zero. Specifically, the entropy of a pure crystalline substance (perfect order) at absolute zero temperature is zero.
