Which of the following statements are true as a block of ice melts? check all that apply.
a. the temperature of the ice/water system remains constant.
b. heat energy leaves the ice/water system.
c. heat energy enters the ice/water system.
d. the temperature of the ice/water system decreases.
e. the temperature of the ice/water system increases.

a. The temperature of the ice/water system remains constant.

c. Heat energy enters the ice/water system.

Explanation:

As we know that when ice coverts into the water then it is known as phase transfer. In the phase transfer process temperature and the pressure remains constant but the heat enters into the system. This heat is responsible for melting the ice. The heat is taken by ice is known as latent heat.

Therefore the option "a" and "c" are correct.
