Can someone give a definition of the first law of thermodynamics?

It's conservation of energy: energy is can't be created or destroyed. So the total energy of a internal system remains constant.

Heat energy, like all energy, can't be created or destroyed, also known as conservation of matter.

Conservation of energy, a function of heat and work. Delta U= q+w.

The first law of thermodynamics discusses conservation of energy. Energy can't be created nor destroyed.

The definition of the first law of thermodynamics is that energy cannot be created nor destroyed. this allows us to calculate the enthalpy of a reaction, predict it using bond energies, etc. hope this helps!

It's just the one that states the conservation of energy.

Energy is neither created nor destroyed. That is why it is known as conservation of energy.

The First Law of Thermodynamics states that heat is a form of energy, and therefore is subject to the principle of conservation of energy. Meaning that heat energy, just like energy cannot be created or destroyed.

The first law of Thermodynamics states that heat is energy and in relation, cannot be created or destroyed.
