THERMAL ENERGY

THERMAL ENERGY

• the energy of heat
• the heat comes from the movement of tiny particles in the object
• the faster the particles move, the more heat they produce

THERMAL ENERGY

• Can move across a systems boundaries
• uunlike other energies its harder to be converted into other energies
• a machine like an engine is needed to convert it
• three main ways thermal energy is transferred: conduction, convection, radiation

THERMAL ENERGY

• The movement of thermal energy into or out of a system is called heat
• since heat is a process, an object doesn't contain heat, it contains thermal energy
• convection- when thermal energy is transferred between gas and liquids

THERMAL ENERGY

• The process of gaining thermal energy is called heating
• conduction- the transfer of thermal energy between matters of different temperatures

THERMAL ENERGY

THERMAL ENERGY

• Thermal energy from the sun keeps the earth at a habitable temperature
• heat from Earth thats lost to space, is replaced by heat brought by the Sun.
• Thermal energy is transferred to the Earth from the Sun through radiation.

THERMAL ENERGY

• Humans have discovered a way of making other forms of thermal energy
• stoves
• matches
