heat and temperature

• Heat is a measure of energy in the particles. Heat is the total thermal energy of the vibrating particles in an object.
• Temperature is the average energy of the particles in an object.
• Conserved - the total quantity of energy that stays the same.
• Thermal energy moves from hotter places (high temperature) to colder places (lower temperature).
• Feeling cold is because thermal energy is transferred away. The energy is transferred away by conduction, convection and radiation.
• When thermal energy moves from a hotter place to a colder place, the thermal energy has dissipated from the hotter place.
• Laws of conservation of energy:

  • Energy cannot be created or destroyed
  • Energy may change form, but the total amount remains the same.
