Law of Conservation Energy

Postby 504999222 » Sun Feb 09, 2020 6:36 pm

Just to clarify in the Law of conservation Energy, energy cannot be gained or lost, it can only be converted from one form to another?

Yes, energy is neither created nor destroyed, but it can be transformed or transferred. It is conserved over time.

Yes, deltaU= q+W = 0 for an insolated system in an isolated universe demonstrates this.
Energy is neither created or destroyed, q= -w

This law is applied to isolated systems, but since the universe is basically an isolated system, it applies to the whole universe as well.

Energy can be gained or lost by a system, however, it always is gained or lost by another system in an equal amount, so it is conserved because it was neither created or destroyed.

Yes, the energy is converted and will be conserved throughout reactions.
