SCIENCE: THERMAL ENERGY UNIT TEST:

Question

IN WICH CASE WOULD THE KINETIC ENERGY OF PARTICLES BE INCREASING?
1. METAL IS MELTED AT 1.300 C
2. METAL IS HEATED FROM ROOM TEMPERATURE TO 200 C
3. METAL IS COOLED AT 1,300 C
4. METAL IS AT ROOM TEMPERATURE, 37 C

Answer 1

In the case where the metal is heated from room temperature to 200°C, the kinetic energy of the particles would be increasing.
