Conduction
Fichas del conjunto (10)
- 1What is conduction of heat?The process by which vibrating particles pass on their kinetic energy to neighbouring particles in a material
- 2Why do materials with small intermolecular distances make good conductors?They form tightly packed structures allowing more neighbouring particles to influence each other
- 3Why are liquids and gases less efficient than solids at conduction?because of the greater atomic distances
- 4What are poor conductors of heat called?insulators
- 5Why are metals good thermal conductors?Their ions are tightly bound, with small distance between neighbouring ions, and they have free electrons that can move inside the metal and collide with other electrons transferring energy
- 6Why are non-metals not so good at conducting heat?They do not have free electrons so are restricted to conducting hat purely through the vibrations of neighbouring atoms
- 7What factors affect the rate of conduction through an object?The material, the state, surface area, temperature difference, and length
- 8How does surface area affect the rate of conduction?The bigger the surface area of an object the more room there is for particles to collide, so the rate of conduction is higher
- 9How does temperature difference affect the rate of conduction?The greater the temperature difference between two objects, the higher the rate of heat conduction between them
- 10How does the length of an object affect the rate of conduction?The longer a conductor is, the longer it takes for heat to pass from one side to the other so the lower the rate of conduction
