• Therm is the non SI unit of heat, Just as Celsius and Fahrenheit are of the temperature.
S4. (b)
• The S.I. unit of the temperature is Kelvin(K).
S5. (d)
• Capacitance is Used in a circuit to block the DC current.
• It has the ability to Store electrical energy.
S6.(a)
• Gas molecules have larger coefficient of expansion than liquid.
• Hence for a small amount of heat, they show greater volatility.
S7. (b)
• Cryogenics is the branch of physics which deals with the production of materials at very low temperature.
S8. (a)
• The colour of the Star depends on it’s surface temperature, as at dry temperature star’s emitted frequencies of different colours.
