Answer 2

Answer:

I ur talking about change of state of matter so

as we know that there are 3 states of matter they are solid liquid and gas so when we heat solids they melt to become liquid and liquid are heated to get vaporise and gases ko heat heat karkne se unki state change ni hoti but we cool gases( condense) they will become liquid and if we cool liquid they will become solid but cooling se solids ki state change ni hoti

so these processes were change of state of matter.
