WAEC - Physics (1996 - No. 16)
Which of the following statements is not correct?
Heat energy can be transformed into mechanical energy
That total heat content of a body is the sum of the kinetic energies of its molecules
lf a body is heated, its molecules move faster.
lf a body is cooled, molecular movement remains constant.
説明
Option D is incorrect because when a body is cooled, the kinetic energy of its molecules decreases, leading to slower molecular movement.
