Heat and Energy in Science

 Good afternoon everybody! today you will be learning about heat and energy and particles and conduction etc. If you need help, you can also visit  Study Jams where you can check out a video, also remember to comment!

 (there will not be a test!)

Science study notes for science test pg.1

·       Thermal energy- energy due to moving particles that make up matter.

·       Energy- the ability to change something or do work

·        Energy fact #2- All changes need energy

·       Particles- particles in a solid are very close together, particles in a liquid are close together but can move past each other. The particles on a gas are far apart and move in many directions

·        Particles #2 - Moving particles make thermal energy

·       Thermometer- a tool used to measure temperature

·       Heat- total energy of moving particles in matter

·       Temperature fact #2-  measures the average energy of the matter

·       Thermal energy fact #2- measures the total energy of the moving particles

Science study notes for science test pg.2

·       Conduction- the transfer of heat energy by one thing touching another

·       Conductor- a material that readily (easily) allows heat to move

·       Insulator- a material that limits the amount of heat that passes through it

·       Convection current- a pattern of flowing heat energy; formed when heated fluid expands

·       Radiation- energy that is sent out without particles

Facts and helping stuff

·       All changes need energy

·       All matter is made of tiny moving particles

·       Particles move faster as the object becomes hotter

·       Particles move slower as the object becomes cooler

·       Moving particles make thermal energy

·       Thermometer is a tool used to measure temperature

·       Liquid particles move closer together when the matter’s particles slow down, this causes liquid to move down the tube

·       Difference between heat and temperature are the movement of the particles of matter

·       Heat is the transfer of thermal energy from one piece of matter to another

·       The greater the amount of particles matter has, the more inertial energy it contains

·       Thermal energy moves from warmer areas to cooler ones

·       In convection a fluid moves from place to place
