A solid material is supplied heat at a constant rate. The temperature of material is changing with heat input as shown in the figure. What does the slope of DE represent ?

A

Latent heat of liquid

B

Latent heat of vaporization

C

Heat capacity of vapour

D

Inverse of heat capacity of vapour

Text Solution

The correct Answer is:
D
`dQ = CdT`
`:. (dT)/(dQ) = 1/C = "Slope of T - Q graph". `

A solid material is supplied with heat at a constant rate. The temperature of the material is changing with the heat input as shown in the graph in figure. Study the graph carefully and answer the following questions: (i) What do the horizontal regions AB and CD represent? (ii) If CD is equal to 2AB, what do you infer? (iii) What does the slope of DE represents? (iv) The slope of OAgtthe slope of BC . What does this indicate?

When we raise the temperature of a body, the molecules and atoms move with greater kinetic enery. Assume that "the temperature" is the manifestation of only the kinetic energy is atomic and subatomic levels and no mass change (excess//defect) occurs due to heating. Now a solid material is supplied with heat at a constant rate. The temperature of the material is changing with the heat input as shown in the graph. BC and DE are parallel to the Heat-input axis In BC and DE

A solid material is supplied with heat at a constant rate. The temperature of the material is changing with heat input as shown (i) AB: change of state from solid to liquid. CD: change of state from liquid to vapour (ii) When CD=2AB , i.e., latent heat of vapourization is twice the latent heat of fusion of the substance. (iii) The reciprocal of slope of DE represents the heat capacity of vapour state of substance . (iv) If slope of OAgt slope of BC, i.e., specific heat of liquid state is greater than specific heat that of solid state.
