temperature and energy Flashcards
what is energy
energy is a quantity to show ability of an object, to cause change by applying forces to it’s surroundings
chemical energy
energy stored in fuels and food
elastic potential energy
energy stored in things that are squashed or stretched
electrostatic energy
energy stored between electrical charges
gravitational potential energy
energy stored in objects that are high up
thermal energy
energy stored in particles of a heated object
kinetic energy
energy stored in a moving object
nuclear energy
energy stored within an atom
magnetic energy
energy stored between magnetic objects
what is the law of conservation of energy
energy cannot be created or destroyed, but can be transferred
heating
due to temperature difference caused electrically or by chemical reaction
electrical
charges moving due to a potential difference
radiation
energy transferred as a wave
eg. light and infrared - the sun emits light radiation and infrared radiation
mechanical
a force moving an object through distance
what is temperature
temperature is the energy per particle
