What is another name for the law of definite proportions?

Answer and explanation

Correct answer: Law of constant composition

The law of definite proportions states that a pure chemical compound always contains the same elements in the same fixed ratio by mass. For example, water contains hydrogen and oxygen in a constant composition, no matter where the sample comes from or how it is prepared. The word definite means fixed, while composition refers to the elements and their proportions in the compound.

Because the law describes a fixed or constant composition, it is also called the law of constant composition. The pressure-volume law concerns gases, evaporation is a physical change, and thermal conductivity concerns the transfer of heat. None of these names describes fixed elemental ratios in a compound. Therefore choice C is the correct alternative name.
