According to the Particulate Theory of Matter, when matter is heated up, its particles gain energy, and thus, it changes its state.
A solid has particles that are tightly packed together. When it is heated, its particles will gain energy and be more spread out to become a liquid. It works likewise for liquids to become gases.
The scientist is most likely observing the liquid state of matter.
Solids.
A spider web is a solid state of matter. It is made up of protein strands produced by spiders called silk, which solidify when exposed to air.
Oxygen is typically found in the gaseous state at room temperature and pressure.
Equilibrium
I believe "heat"To change from one state of matter to another state of matter heat is added or taken away.I think that makes sense!
The state of matter remain unchanged.
no physical change does not change matter
Change of state.
state of matter
The state of matter remain unchanged.
a change in size, shape or the state of matter is a physical change. True for A+.
It can.
atoms
Because melting is a change of state: from solid to liquid.
A change in the state of matter occurs when heat energy is added or removed.
phase change.
