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.
As a substance heats up, the particles become more active.
they move faster, eventually changing the solid into a liquid
The dimension of the sample increases; the chemical composition remain unchanged.
It's particles move faster
It gets warmer.
the substance will expand
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
It will explode due to a large Expansion of the particles
The distance increases, as the particles become more energetic and the substance loses its definite volume, as the particles bounce around, due to heat/increased energy.
When a substance dissolves in water, water molecules get between the particles of the dissolved substance, separating them.
Both the mass and weight remain unchanged. However; generally; the volume increases due to the thermal expansion of the substance when heated up.

Particles or electromagnetic radiation are emitted.
yes! particles of a substance assume different shapes and sizes
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 particles are affecting the form of a chemical substance and not turning into a new substance.
Particle Movement decreases.
Thermal expansion occured.
Heat affects the properties by speeding up the particles and providng them with more energy. As they heated the bounce off one another and expand the solid. When it's cold, The particles have less energy and don't move as much, This results in contraction and the solid shrinks. Basically, Heat ---> expansion Cooling -----> contraction
