Which amongst the following were implications of Joule's experiment, as discussed in the previous problem?
Which amongst the following were implications of Joule's experiment, as discussed in the previous problem?
The correct options are
A Heat is another form of energy and not a mysterious liquid which controls the temperature of materials
B The law of conservation of energy is universal and inelastic collision is not an exception
D Found the equivalence between the unit of heat ('calorie' until then) and unit of work (Joule)
Joule's experiment proved that mechanical energy and heat are equivalent. This debunkedmany earlier assumptions and also strengthened some of the exisiting theories.
Since mechanical energy and thermal energy are the same, the apparent disappearance of energy during an inelastic collision could now he explained.
All of these implications lead to the first law of thermodynamics which equated the thermal energy added to the system (Q) to the sum of the work done by the gas and the increase in its internal energy (which is directly proportional to its temperature).
