Past Paper MCQ
The balloon is filled with:
Correct Answer: A. Helium
One-liner
Balloons are typically filled with Helium because it is lighter than air and non-flammable.
82.
What is the chemical formula for laughing gas?
Correct Answer: B. N2O
One-liner
The chemical formula for laughing gas is N2O (nitrous oxide).
83.
LPG mainly contains _?
Correct Answer: A. Methane, Butane and Propane
One-liner
LPG mainly contains Methane, Butane and Propane.
84.
The particles in Gas have the following movement?
Correct Answer: D. Both A and B
One-liner
Gas particles move in random motion in all directions at high speed (translational motion) — both A and B are correct.
85.
The behavior of a gas is non-ideal at?
Correct Answer: C. Low temperature and high pressure
One-liner
The behavior of a gas is non-ideal at low temperature and high pressure because intermolecular forces and molecular volume become significant under these conditions.
86.
Which gas is commonly used as a coolant in cold storage facilities?
Correct Answer: A. Ammonia
One-liner
Ammonia is commonly used as a coolant in cold storage facilities due to its excellent thermodynamic properties and high latent heat of vaporization.
87.
Past Paper MCQ
Which of the following gas is combustible?
Correct Answer: D. Hydrogen
One-liner
<strong>Hydrogen</strong> is a combustible gas that burns readily in the presence of oxygen to produce water.
88.
All of the following are uses of nitrogen gas EXCEPT?
Correct Answer: A. It is used in the baking industry
One-liner
Nitrogen gas is not used in the baking industry; baking powder and baking soda (which release carbon dioxide) are used instead.
89.
Gases conduct electricity at _?
Correct Answer: B. Low pressure
One-liner
Gases conduct electricity at low pressure because reduced pressure allows free movement of ions and electrons, enabling electrical discharge.
90.
What is the solid state of carbon dioxide commonly called?
Correct Answer: D. Dry ice
One-liner
The solid state of carbon dioxide is commonly called dry ice.
