Which of the following cannot conduct electricity?
- NaCl (Solid)
- NaCl (Molten)
- NaCl (Aqueous)
- Both B & C
- a
-
In NaCl, Ions are fixed in place or in solid form and cannot move.
In NaCl (Molten / Melted), Ions are free to move and electricity can flow.
NaCl (Aqueous / dissolved in water), Na and Cl can dissolved in water and can carry current.
CaCo3 is a polymorph and exist in two crystalline form:
Viscosity of liquid increases with the decrease in:
- Temperature
- Intermolecular forces
- Atmospheric pressure
- Molecular mass
- a
-
Viscosity is the resistance of liquid to flow.

SCUBA is a breathing apparatus which contains:
- 50% Nitrogen and 50% Oxygen
- 96% Helium and 4% Oxygen
- 96% Oxygen and 4% Helium
- 78% Nitrogen and 21% Oxygen
- b
-
SCUBA stands for Self Contained Underwater Breathing Apparatus. It is used for breathing underwater.
Pure mixture of 50% both is dangerous.
Normal ratio of both is not used for deep depth.
Maximum Helium as 96% is used in deep dive to prevent from Nitrogen Narcosis.
Too much Oxygen is dangerous.
