Heat Transfer In Metal Rod

  1. Heat Transfer In Metal Rodent
  1. Convective Heat Transfer - Heat transfer between a solid and a moving fluid is called convection. This is a short tutorial about convective heat transfer; Cooling Mode - Heat Flux - Heat fluxes for various cooling or heat transfer modes; Cylinders and Pipes - Conductive Heat Losses - Conductive heat losses through cylinder or pipe walls.
  2. The energy from the hot water makes the molecules of the metal rod move faster, which we can feel as the rod heating up. The heat spreads up the rod as the faster molecules at the end of the rod bump into adjacent molecules and give them energy too - so the middle of the rod (even though it was not touching the water) got warmer as well.

1.Thermal Conductivity of Metal Rod Apparatus

When you put the metal teaspoon into the hot tea some of the thermal energy from the tea is transferred to the metal particles. The metal particles start to vibrate faster and collide with their neighbouring particles. These collisions spread the thermal energy up through the teaspoon. This makes the handle of the teaspoon feel hot.
