Which of the following statements is not correct?
A
Heat energy can be transformed into mechanical energy
B
That total heat content of a body is the sum of the kinetic energies of its molecules
C
lf a body is heated, its molecules move faster.
D
lf a body is cooled, molecular movement remains constant.
Verified Correct Answer: D.
Physical Principles & Numerical Solution
