yes, the heat makes the particles move and in the heat they expand.
Yes, because all of the particles inside of the solid separate so that cause the solid to expand.
Solid.
It depends on the solid.
If the food has water in it then it will expand.
The scale is assumed to expand and contract with the solid - you cannot measure a solid with a 30cm ruler from another continent.
All of them can expand - for example, when they are heated. Gases usually expand more than solids or liquids.
The particles in a solid, move very little. But when it is heated, the particles expand because the heat moves the particles around more, making them need more space to move, therefore expanding the solid. =)
This is becuase it becomes a solid and the particles expand to fit neatly into a solid square.
When a solid absorbs heat, its particles gain energy and begin to vibrate more rapidly, causing the solid to expand. This expansion may lead to a change in state, such as melting if the temperature reaches the solid's melting point.
When heat is added to a solid, its particles start vibrating more rapidly, increasing their kinetic energy. This causes the solid to expand slightly as the particles spread out. If enough heat is added, the solid may reach its melting point and turn into a liquid.
ne heat gives energy for the particles to move around
gas expand more than liquid and liquid expand more than solid.
