Answer:
more kinetic
Explanation:
I think the kinetic energy is 75 percent while the potential energy is 25 percent
It describes how, when particles/mc/elements react, despite forming different substances the mass is neither created nor destroyed but only converted.
Answer: Matter is heated, and its particles spread out more
Explanation:
Thermal expansion occurs when there's an expansion of an object or material or when an object becomes bigger because of a rise in its temperature. This brings about the faster movement of the heated molecules and the atoms spreading out.
Therefore, the cause and effect of thermal expansion will be that when matter is heated, and its particles spread out more.
Answer:
Number of moles (n)=
molecular weight
weight
Weight=n×Molecular weight
=0.5×14
Mass=7g
