A throttling process (valve) for an ideal gas results in:

A Temperature change

B No temperature change (constant enthalpy)

C Pressure increase

D Volume decrease

✓ Correct Answer: Option B

Throttling is isenthalpic (h₁ = h₂). For ideal gases, h depends only on T, so T remains constant.

💡 Why is B) the correct answer?

The correct answer to the question "A throttling process (valve) for an ideal gas results in:" is Option B: No temperature change (constant enthalpy).

The other options — A) Temperature change, C) Pressure increase, D) Volume decrease — are incorrect for this Everyday Science question. As explained above: Throttling is isenthalpic (h₁ = h₂). For ideal gases, h depends only on T, so T remains constant.
