​​

Answer:

heating and reversible

Answer 2

Diagram has been attached !

• So, in the given flow chart we can very easily understand that it represents the change in states of water, ice and steam.

I will label the names of the various processes in the flow-chart :

• P : MELTING

• S : FREEZING

• T : BOILING/VAPOURISATION

• R : CONDENSATION

MELTING:

• This is a process of changing of state from ice (solid) to water (liquid).

• The temperature at which the change in state of affairs is known as the melting point.

And since these processes are physical processes, ALL OF THEM ARE REVERSIBLE.
