Why do steel bars expand when heated make use of kinetic theory of matter to support the answer?

The temperature of steel is determined by the amount of vibration of its constituent atoms. Hotter atoms vibrate more. And when they vibrate more, they take up more space. Hence, the steel expands.

As sample of matter is heated it's particles do what?
As the individual atoms are warmed up, they move faster causing the substance to expand slightly. As a substance has energy added to it through heating, its Kinetic Energy becomes greater. Kinetic energy is the energy of Motion - the more the kinetic energy of the atoms of a substance means the faster the speed of motion of these same atoms.
When a substance is heated it must gain electrons and energy?
Yes, it gains kinetic energy, for instance, when water is heated into water vapours the molecules of water vapour move faster than the molecules of water. This is because the water vapour has more kinetic energy than water.
What happens to most matter when heated?
When matter is heated the particles in the matter gain energy and begin to move or vibrate more depending on the state in which the matter is currently in. If the heat provided is significant enough they can change state too. Hope that was what you were looking for!
What theory of matter states that all of the particles that make up matter are constantly in motion?
kinetic theory.
Does particles in gases expand when heated?
This is because when heat is applied to particles, they gain energy, therefore they travel faster and space out. The volume will increase though the density will decrease. So matter will always expand when exposed to heat.
What happens to matter when heated?
When matter is heated it will expand
Does matter contract or expand when heated?
Matter expands when it is heated.
Does matter expand or contract when it is heated?
Expand
Does matter expand or contract when heated up?
Matter expands when it is heated.
Does matter expand or contract when it's heated?
Expand
What happens to matter when it is heated SCIENCE?
It will expand.
Do atoms get hotter when matter is heated?
When a matter is heated then the vibration of atoms increase and hence the kinetic energy increases.
What does most matter do when heated?
Most matter EXPANDS when heatedmost matter expands when heated
Does the atom gets hot when the matter is heated?
When a matter is heated then the vibration of atoms increase and hence the kinetic energy increases.
Why matters expand when heated?
Matter expands when heated, because molecules move farther apart.
Which state of matter expands the most when heated?
Gases. Their molecules are already the farthest apart compared with solids and liquids, and small changes in temperature causes these loose molecules to absorb the kinetic energy of the heat and expand. If not bound by a container, the gas can expand indefinitely into the atmosphere.
What happens when a solid is heated using particulate theory of matter?
The solid will expand.
