88
95% (by volume) of LPG at 760 mm Hg pressure will evaporate at __________ °C.
Discuss
Answer & Solution
Answer: Option A
Solution:
LPG (Liquefied Petroleum Gas) is mainly a mixture of propane and butane, and its volatility is controlled through standard specifications.

The 95% evaporation temperature at 760 mm Hg (atmospheric pressure) is an important quality parameter that ensures proper vaporization and limits the presence of heavier hydrocarbons.

According to standard specifications (such as ASTM/IS standards), for commercial LPG (especially butane-rich mixtures), the 95% evaporation temperature is around 2°C.

-40°C corresponds approximately to the boiling point of propane and does not represent the 95% evaporation condition of commercial LPG mixtures.

Higher values like 30°C and 55°C indicate the presence of heavier components, which are undesirable in LPG.

Therefore, the correct answer is 2°C.
