Question

Change in the state of matter can be brought by changing :

• A. temperature
• B. pressure
• C. A or B
• D. none of these

Answer 1

Answer: (C)

A or B

Matter changes from one state to another by changing temperature or pressure. We can convert matter from one state to another by adding or removing energy(heat), i.e, by changing temperature. Or by changing the pressure we can bring the molecules closer or take them far apart. This also can change the state of the matter.
