Question | Answer |

Why does ice melt PO | * The thermal energy of the air transfers to the ice causing temperatures to rise particles are moving faster causing melting of ice into water |
Why does ice melt PT | Thermal energy moves from warmer to colder increases motion of particles of the cooler object until both of chips of the same temperature |
Heat | The transfer of thermal energy from warmer objects to cooler ones |
Conduction | The transfer of thermal energy that results from collision of part two calls via physical contact ;hotter to cooler p |
Convection | Transfer through energy via a fluid or gas Derives from a term that means to carry Change is the density of particles of a fluid and current develops |
Radiation | Transfer of thermal energy as waves or currents in the air two objects must connect EX the sun in skin on beach |
Insulation | Comes from the Latin word meaning to insula; island this is the idea that an island and more insulated substances that conduct thermal energypoorly |
Insulation PT | Insulation prevents warmer inside air from trying to get to colder outside air |
Insulation P3 | Insulation prevents warmer outside air from trying to get inside the house |
Static energy one | Is a great derivative static means standing |
Static energy two | Static means without motion or at rest |
Static energy three | Therefore static electricity is electricity that is standing or does not move all the time |
Static energy four | It's temporary and unpredictable |
Static energy five | Science definition the electric charge builds up on an object that has gained or lost protons |
Static energy six | When static electricity is producing negative chart movement this is because electrons are on the outside of an atom |
Static energy seven | The direction of static electricity is always from negative surface to a positive surface because only negative charges have the ability to move |
Why are dryer sheets important | Clothes that cling have opposite charges that sheets prevent the buildup of negative charges on clothes |
Circuit | A continuous path through which electric charge flows |
Series circuit | A series in which there is only one path for the current to flow |
Parallel circuit | A circuit in which there is more than one path for the current to flow |
Electromagnetic | A temporary magnet that is made by passing on electric current through a coil of wire that surrounds an iron core |
Sequence of a lightbulb step one | Flip a switch |
Step two | Wires touch |
Step three | Charge flows from wires to bulb |
Step four | Charge flows through filament in bulb |
Step five | Filament grows |
Step six | The flow of charge must go back to switch there another internal wire |
