During the process of melting from a solid to a liquid, what happens to the temperature of the substance?
a. it stays constant.
b. it increases
c. it decreases
d. it increases and then decreases.

It is A

Explanation: Melting occurs when a solid is heated and turns to liquid. The particles in a solid gain enough energy to overcome the bonding forces holding them firmly in place. This is called freezing and occurs at the same temperature as melting. Hence, the melting point and freezing point of a substance are the same temperature.

B. it increase

Explanation:

it increase cause if you put more temperature, the molecules would move more quickly leading to solid become a liquid.

i hope its help

answer; ///as energy flows through an ecosystem,energy (decreases) at each

answer: land bridge theory. land bridge theory held that shifting portions of dry land explained the finding of identical species on different continents. plate tectonic theory eventually eliminated the land bridge theory.
