Tutor description

1. Atoms rotate and translate (move in a straight line), hence they have kinetic energy. 2. Atoms also have latent energy (potential energy) due to their bonds. 3. The internal energy of an object is made up of kinetic energy and potential energy. 4. Temperature measures internal energy. Symbol:  5. Why does evaporation produce cooling?

The internal energy of an object is made up of kinetic energy and potential energy.4. Temperature measures internal energy. Symbol: 5. Why does evaporation produce cooling?During evaporation, the more energetic molecule (more kinetic energy) escapes from the water surface. The total amount of internal energy in the remaining molecules therefore decreases. Since temperature measures internal energy, if internal energy decreases, temperature will also decrease. (Cooling takes place)6. Differences between evaporation and boiling7. Factors affecting rate of evaporation:TemperatureHumiditySurface areawindpressureboiling point8. Light1. Light moves via:Reflection(light bounces back)Refraction(Lights bends)Lenses(Light converses)2. ReflectionLaws of reflection:A. The incident ray, the reflected ray and normal, at the point of incident, all lie in the same plane.B. The angle of incident is equal to the angle of reflection.3. A.ir4. Characteristics of the image of a plane mirror:VirtualSame sizeLaterally invertedUprightObject distance is the same as image distance5. 6. Refraction:The bending of lig
