In following diagram A, B, C, and D (assume left most A and so forth with right most D) the arrows are showing –

• Decrease in energy thus more particle movement during change in state of matter
• Increase in energy thus less particle movement during change in state in state of matter
• Decrease in energy thus less particle movement during change in state of matter.
• Increase in energy thus more particle movement in each new state than before during the change in the state of matter.
