-After observing all energy demonstrations listed below,write a preliminary working definition ofenergy.
The energy demonstrations are:
1. beaker of water brought to boil over a hot plate orstove.
2. viscous heat pack (you have all seen them work, you do not haveto buy one unless you do not know how they work.
3. popcorn to be popped and eaten (great with your loved one and amovie).

1 Here what stove is doing is converting chemical energy to heat energy by burning which is absorbed by water to make them boil then it is used as transition energy to convert to steam 2 Working of viscous heat pack is the dissipation of mechanical energy in a viscous fluid Generally the rate of viscous heat generation depends on the shear rate 3 we give energy as heat to the cop which is See Answer
