it's from my chapter 6 heat and energy of physics....(Selina icse )
here it goes: is heat obtained due to the random motion of molecules or the molecules come in motion when heated ... please reply ...​

Answer 1

Answer:

Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects is called heat.

Answer 2

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Mass of the object remains the same, however solids, liquids and gases all expand when heat is added.
