As a substance heats up, the particles become more active.
As you might expect from the term "expansion", they get farther apart from each other - at least on average. They also tend to gain more vibrational energy, rotate faster (when able to) and move around faster in general.
The chemical makeup changes in the substance.
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
The liquid rises, indicating a temperature.
It gets hot and undergoes thermal expansion.
It's particles move faster
Particles or electromagnetic radiation are emitted.
This varies depending on the substance What happens to the particles in substance B if they change state to substance
the subtance cannot be changed back to its form
Boiling occurs when the intermolecular forces holding a substance in the liquid state become overwhelmed and allow the particles to separate into the gaseous state. Particles in the gaseous state are roughly 2000 times farther apart than in the liquid state, which causes expansion of the substance in its gaseous form.
The movement is accelerated.
The particles move apart and move faster
The particles are affecting the form of a chemical substance and not turning into a new substance.
The particles in the substance slowly separate and when the substance is a gas the particles are free, and are buzzing all over the place
Particle Movement decreases.
Thermal expansion occured.
it is when particles react to the substance in which it has been placed with
The bonds in between the particles become weakly bonded.
When a substance changes from a liquid to a gas, the kinetic energy of its particles increases.
Particles move faster when heated. When cold, they move slower.
By heating, you are adding energy. The particles will vibrate(move) faster.
The particles move more quickly and begin to move from place to place
when a substance undergoes a physical change,its identity stays the same.
A substance gains thermal energy as the temperature of the substance increases, because the particles of the substance vibrate more as this happens.
what happens when an isotope undergoes beta emission?
