What is the scientific law that is the basis for the assumption that the heat energy lost by the a metal as is cools is equal to the heat energy gained by the water and the calorimeter?

The energy transfer within the system (between the water and the lead sinker) must obey the first law of thermodynamics. Meaning, "...that energy can not be created or destroyed, it can only be changed from one form to another or transferred from one body to another, but the total amount of energy remains constant (the same)." So due to the conservation of energy, the heat lost by the lead sinker is transferred to the water in equal amounts. We must assume here that the experiment is well controlled and there are negligible sources of heat transfer from unintended external sources.

∙ 14y agoAssuming you mean a metal completely submerged in water. The water would lose heat to the air. However even if this experiment was in a completely heat resistant material the water would not necessarily gain the same temperature as lost by the metal.
It would gain the same amount of ENERGY lost by the metal which does not always translate into heat.
And even if you assumed some sort of perfect world where it did all translate into heat, the temperature gain would depend on the mass of water.

What are atoms that have gained energy called?
excited state atoms
How is calorimetry related to the law of conservation of energy?
The Law of Conservation of Energy states that energy is neither created nor destroyed but remains constant in a given system. Therefore, wouldn't calorimetry make use of it because the energy gained/lost by the water would cancel out the energy lost/gained by the substance and result in no change overall?

An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
When enough heat energy is gained by liquid water the liquid water can?
molecule
What compound is energy?
Energy takes different forms. Energy is never lost or gained but it can be in the form of heat (atoms moving faster), in changing of state (solid with the least energy, liquid next, and vapor with the most) or at an atomic level (fusion and fission)
What percent of energy is gained by alternative energy?
About 55%to60% of energy is gained by alternative energy.
Knowledge gained by scientific research is?

Does energy lost equal energy gained?
no
When a solid changes to a liquid energy is?
energy is gained!
How much energy is gained by 3 grams of ice when it changes to water?
No energy is gained. On the contrary, energy is required to make ice melt.
When a bond is formed is energy lost or gained?
give out energy
What Knowledge gained by scientific research always?
hell yeah

What sort of energy has the cyclist gained when she reaches the summit?
Potential energy.
What is the process of the water cycle where energy is gained?
I
Is energy gained or lost during vaporization?
Vaporization is an endothermic process. It takes energy to heat up material to the point that it vaporizes, so energy is gained by the material being vaporized and lost by the environment.
