When we raise the temperature of a body,...

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 which of the following phase the assumption made in the above comprehension is most precise ?

A

solid

B

liquid

C

gas

D

not predictable

Text Solution

Verified by Experts
