when materials get hot their molecules get energy,speed up and exert greater force on the edges due to which materials expand.

Dark materials will get hotter in the sun, but smooth shiny metal will get hotter faster when exposed to direct heat like fire. Be more specific with your question.
No. Other stars are much larger and much hotter than the sun. The sun only seems larger and hotter than others because it is the closest star to us.
A red star can be more luminous than a bluish-white star if it is larger in size and/or hotter in temperature. The luminosity of a star is determined by its size and temperature, with larger and hotter stars emitting more energy. Therefore, a red star that is larger and hotter than a bluish-white star can be more luminous.
That's similar to asking, "Why is a boulder heavier than a pebble?" Flames from a larger fire are more concentrated and fuel needing, just like the sun is bound to be a lot hotter than a spark. Fire temperatures vary greatly and generally the larger the fire the hotter. There are rare exceptions, however.
it goes deeper into the earth and gets hotter.
30 degrees Centigrade is hotter than 30 degrees Fahrenheit.

No. Most materials expand when they get hotter. A notable exception is water between 0 and 4 degrees centigrade.No. Most materials expand when they get hotter.

the heart is a little larger than ur fist What does this come from?
Its a definition thing. Gasses don't move more because they're hotter. Gasses that move more are defined to be hotter. Gasses move more when they aquire energy from somewhere and their increased motion is measured with a thermometer. And when the thermometer goes up we say the gas is hotter.
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
