Question

When the internal energy of a material increases,: a) its temperature will rise b) it will go through a phase change c) A and B d) A or B

Answer 1

a or b

Step-by-step explanation:

Answer 2

D. A or B

Explanation: The temperature of a substance cannot increase during phase change, so both A and B cannot happen simultaneously. And internal energy is the sum of the microscopic potential and kinetic energies of a substance, which increase with temperature and phase transition.
