According to Boyle's law, at constant temperature, the pressure of a gas is inversely proportional to its: MCQ with Answer and Explanation

According to Boyle's law, at constant temperature, the pressure of a gas is inversely proportional to its:
A. Density
B. Volume
C. Temperature
D. Mass
Answer: Option B
Solution (By JKSSB Mock Tests)
Boyle's law: P ∝ 1/V or PV = constant at constant T and n. So if volume increases, pressure decreases. This is because gas molecules have more space and hit the walls less frequently. An example is a syringe: pulling the plunger increases volume, decreases pressure.

Question #1
The catalyst used in the Contact process for manufacturing sulfuric acid is:
A. Manganese dioxide
B. Nickel
C. Vanadium pentoxide (V₂O₅)
D. Iron

Correct Answer: Option C


Explanation:
The Contact process involves the oxidation of SO₂ to SO₃. The catalyst used for this step is Vanadium pentoxide (V₂O₅) or sometimes platinized asbestos. Iron is used in the Haber process, and Nickel is commonly used in the hydrogenation of vegetable oils.

Question #2
The Contact process is used for the manufacture of:
A. Sodium hydroxide
B. Ammonia
C. Nitric acid
D. Sulphuric acid

Correct Answer: Option D


Explanation:
Contact process: SO₂ + O₂ ⇌ SO₃ (catalyst V₂O₅) followed by absorption in H₂SO₄ to produce H₂S₂O₇, then H₂SO₄.
