They don't get bigger, they move further apart which causes the material itself to expand.

Why can a jammed metal lid of a jam jar be opened by heating?
When you heat the jar, the glass expands only slightly while the metal expands much more. This is governed by the coefficient of expansion for the substance. The greater the coefficient of expansion, the more the substance expands. Since metal generally has a much higher coefficient of expansion, the lid of the jar will get bigger while the jar only expands slightly. That makes everything a little looser, which makes it much easier to open the jar.
Most matter when heated?
The individual particles vibrate/move faster. The matter as a whole expands.
What is an attraction between particles of the same substance called?
An attraction between particles of the SAME substance is called cohesion.
What is the mixture in which the particles of one substance are evenly mixed with the particles of another substance?
A homogenous mixture
How can you tell that the substance in the container is a gas?
It expands to fill the container.
When substance is heated its particles expand and increase in size?
it expands and it becomes bigger
What happens to a particle of a substance when it expands?
individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with). If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)
What happens to density during the heat expansion of a substance?
Think of of the expanding substance as a box full of marbles. If it expands, they end up in a bigger space (in this case a bigger box). Because of that they have more room to move around and there will be less particles and less mass per cm2 which is what the density is.
Do particles get bigger when they are heated?
The particles themselves don't get bigger, they do however start moving more quickly and therefore they use up more space to move around in. (That's why most stuff expands when you heat it)
When a gas expands whether its density increases or decreases?
the density decreases because the particles spread out and so less particles occupy the same amount of area meaning the substance is less dense.
As a substance changes from a liquid to a gas the space between its particles?
......... distances become 100 to 1000 times bigger
What substance expands when frozen?
water
What becomes bigger in size due to movement of particles in a solid?
If the particles in a substance are moving, the volume of that substance becomes larger because the particles move faster and spread farther appart. the mass of the object stays the same because it is the same amount of particles, just in a format in which the volume is larger. hope i helped :)
What is bigger gas particles or smoke particles?
smoke particles are bigger than gas particles.
What happens to a substance or object when it is heated?
It expands.
What happens when particles are warm?
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.
What happens to two particles which start off near each other as the bubble expands?
the two particles move further apart as the universe expands because I am a beaver
