412 kelvin = 138.85° celsius
Answer: yes
Explanation: its common sense
ANSWER
The temperature at which it boils is a measure of its physical property
STEP-BY-STEP EXPLANATION:
Firstly, we need to define the physical and chemical property of matter
The physical property of matter is characteristic of matter that is not associated with a change in its chemical composition. The physical properties include; <em>color, density, hardness, melting, and boiling point.</em>
The chemical property of matter is characteristic of matter that is associated with a change of matter from one type to another type. The chemical properties include; <em>Flammability, toxicity, acidity, reactivity, etc.</em>
When a liquid is boiled, it changes its state from liquid to vapor, this change of state is associated with the physical property of matter.
Hence, the temperature at which it boils is a measure of its physical property

Explanation:
Dalton’s Atomic Theory
All elements are composed of tiny indivisible particles called atoms.
All atoms of the same element are identical.
Atoms of different elements are different(they have different sizes, masses, chemical properties, etc.).
Atoms of different elements can combine with each other in simple whole number ratios to form compounds. (Law of Definite Proportions).
Chemical reactions occur when atoms are separated, joined, or rearranged. However, atoms of one element are NOT changed into atoms of another element by a chemical reaction. (Law of Conservation of Mass).
