Phet Simulation: Energy Forms And Changes--Intro(Heat)
Procedure:
1. Please go to the simulation through the link:
2. Click “Play” and then choose “Intro” :
3. Check each of the following tasks after completing it.
❏ Use thermometers to measure the temperature of the blocks, the oil, the water
and the heating/cooling units.
❏ Heat up a block.
❏ Cool down a block
4. Check the first box on the up right:
5. Check each of the following tasks after completing it.
❏ Add energy blocks from an iron block to the water tank, try to add as much as
possible.
❏ Move energy blocks from the oil tank away from it, as much as possible.
6. Answer the following questions:
I. The energy blocks moving in the simulation present:__thermal_________energy.
II. When the energy blocks stop moving, the temperatures of two objects
are_decreasing_________.
III. Heat always flow from_warmer___temperature objects to _colder____temperature
objects.
