I hope this maybe the answer for your question and it help the way u wanted to be helped ....
heat energy is used for changing the state not for increase the temperature or decrease...after state was change accordingly it increases or decrease it temperature
Heat is required to change the phase as well as to increase the temperature. During phase transitions, the heat supplied (called the latent heat) is fully utilised to change the state by overcoming the force of attraction between the particles. So, the temperature remains constant during the change of state.hope it helps you dear❤️❤️❤️❤️

hey thethere firstly understand it..
the heat that is supplied during phase transformation is not go to increase temperatures
Let's understand this taking an example of a solid , say ice.
As ice is a solid , it has strong inter molecular forces of attraction ,i.e , its molecules are tightly bind together. When it is heated , the molecules gain kinetic energy and start vibrating . Then , the molecules start going far from each other . This is called melting stage , this is the stage where the solid starts melting into liquid. The temperature remains constant because the heat is being used to break the mutual forces of attraction between solids.
Since the heat is used to overcome the force of attraction, the temperature of the substance does not change. The heat energy absorbed in this case is called as the latent heat. The temperature of the substance remains equal to the latent heat provided to or released by it. That's why for any substance, the temperature remain constant during the change of state.
Hope it helps ; )
The temperature remains constant during the change of state as we usually heat or freeze to change one state of matter to another
When a solid melts to form liquid the temperature remains constant because change in state takes place and the latent heat is used up in overcoming the forces of attraction between the particles of solid.
what to look at the dictionary
we have seen that some stars moves or some do not. the reason it is that the velocity of earth and star.
1) when the velocity of earth and star will be same than the will appear to be rest with respect to earth.
2) when there is difference in velocity of earth and star , the star seems to be moving with respect to earth.
in fact all stars move.
