Conduction and Convection
Two flasks hold colored water, one yellow and the other blue. Set the starting temperature of each flask, choose a type of material to connect the flasks, and see how quickly the flasks heat up or cool down. The flasks can be connected with a hollow pipe, allowing the water in the flasks to mix, or a solid chunk that transfers heat but prevents mixing.

Experiment: Experiment with all six solid chunks.
For each, click Fast forward and then, after about 500 seconds, Pause ( ). Record the temperature of each flask.

Why is the transfer of heat differnet with the hollow pipe depending on if the hotter liquid is on the top vs it on the bottom?

3

Of the 3 things we tested, rank them form the quickest from of heat tranfer (at the top) to the slowes)

  1. Convection (when hottest item is in the bottom)
  2. Conduction
  3. Convection (when the hottest item is on the top)
Radiation
Use a powerful flashlight to pop a kernel of popcorn. A lens focuses light on the kernel. The temperature of the filament and the distance between the flashlight and lens can be changed. Several obstacles can be placed between the flashlight and the popcorn.
