By the first law of thermodynamics, energy is conserved - i.e. the sum of the useful work and the energy lost to heat will equal the energy you started with.

The second law states that you will never get 100% energy efficiency.

The first law of thermodynamics is the law of conservation of energy. They are the same thing.

The first law of thermodynamics states that the energy within a closed system is constant regardless of changes in that system. The law of conservation of mass and energy states that total mass and energy (in a closed system) will always remain the same despite changes inside of the system.

Better rephrase the question. Thermodynamics is a branch dealing with the heat energy given to a system and the increase in its internal energy and work performed by the system. Where as, the mass which is also defined as quantity of matter is not related so directly to the quantity of heat energy given to the system.

As stated by the expert:

The First Law of Thermodynamics IS the Law of Conservation of Energy.

The Second Law of Thermodynamics is not directly related; however, it provides additional restrictions, as to what can, and what cannot, be achieved.

Because energy can be converted to mass and vice-versa in nuclear reactions such that e=mc2 therefore mass and energy can be considered to be the same

Law that states that energy cannot be created or destroyed?

The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.

Thermodynamics first law?

The first law of thermodynamics states that in any thermodynamic process, when heat Q is added to a system, this energy appears as an increase in the internal energy stored in the system plus the work done by the system on it's surroundings. or to shorten that, energy can neither be created nor destroyed, but it can change from one form to another i hope this helped ^^

As water spontaneously freeze at room temperature the floor becomes very slightly cooler which law of thermodynamics has been violated?

That would significantly violate the second law of thermodynamics. For water to spontaneously freeze at room temperature, there would have to be something colder than the freezing point to absorb the energy coming out of the water. If the floor also became cooler, then it could not be absorbing energy. If you had ONLY the water and the floor, then this would also violate the 1st law - conservation of energy.
