the hot chocolate in the large pot has more therma energy than the hot chocolate in the mug
Acceleration = change in velocity / time
= 40 mi/s / 2s = 20 mi/s/s
Answer:
Sound can't travel in a vaccum.
Explanation:
Sound waves need a medium in order to travel (e.g. air, water, glass)
Since there was a vaccum between the glass the sound couldn't travel since vaccum's contain a very small amount of atoms.
The mass is the same since the number of each type of atom in the vessel is constant when the mass of vessel 5 at 127°c compare to its mass at 27°c.
<h3>Law of conservation of mass:</h3>
According to the law of conservation of mass, mass is conserved, meaning that the total mass that was there before a chemical reaction is the same as the total mass that was present after the chemical reaction. In his combustion experiment, Lavoisier found that the mass of his original substance—a glass vessel, tin, and air—was equal to the mass of the produced substance—the glass vessel, "tin calx," and the leftover air.
This led him to formulate the rule of conservation of mass. The number of atoms should not change; only their arrangement can produce a new molecule or complex.
