Thermal energy depends on the movement of
particles of matter:
►When the water is heated, its particles move
faster and transfer thermal energy between each
other in the form of heat.
►When the thermal energy of particles increases
this leads to change in the temperature and the
state of water.
glassblowing
❶ Manufacturing of glass depends on
changing the glass from one state to
another.
❷ When the glass (solid state) is heated
at very high temperatures, it changes
into molten glass (liquid state)
❸Then, the molten glass is cooled
forming different shapes of glassware.
What Do You Already Know About the thermal energy?
.Everything around us is made of matter
.Matter can change from one state into another
•All matter is made of particles called atoms and molecules.
