Physics - ICS Part 1 Physics Chapter 11 Short Questions Test

Question # 1

We talk about molar specific heat of gases but not talk about molar specific heat of solids and liquids. Why?

  • Ans 1: In case of solids and liquids the change in volume and hence work done against external pressure during a change of temperature is negligibly small.But same can not be said about gases which suffer variation in pressure as well as in volume with the rise in temperature.

Question # 1

Define absolute zero using the Carnot cycle.

  • Ans 1: The Carnot cycle provides us the basis to define a temperature scale that is independent of material properties, Absolute zero is the lower limit of the thermodynamic temperature scale, a state at which the enthalpy and entropy of a cooled ideal gas reaches its minimum value, taken as zero(0). By international agreement, absolute zero is taken as - 273.15°c.

Question # 1

Why does the pressure of gas in a car tyre increase when it is driven through some distance?

  • Ans 1: When a car is driven through some distance on the road, its tyres has to overcome frictional force of the road. The work done against the friction heats up the gas in tyre. It increase the velocity and hence the pressure of the air in the tyre.
