1.2 specific heat capacity

  • you can see my previous notes at heat pls ty
  • small amount of water in a kettle will experience greater change in temperature than a large volume if heated for some time.
  • metal object gets hotter faster than a wooden object.
  • large heaters warm rooms faster than small ones.
  • the significance of these observation is that mass, material, and the amount of energy transferred influence any change of temperature.

changing temperature

  • temperature of a substance is measure of the average kinetic energy of particles inside the substance.
  • greater the mass of substance, greater the energy required to change kinetic energy - so heat required to raise temperature by a given amount is proportional to mass of substance.
