Answer:
An atom is the smallest particle of an element that can take part in a chemical reaction while a molecule is a group of chemically combined atoms.
Explanation:
You could compare it to Washington D.C. It runs the cell as our capitol runs our government. It can be the "heart" of the cell. <span />
Answer:
Systems of measurement in use include the International System of Units (SI), the modern form of the metric system, the imperial system, and United States customary units.
Answer: An atom in an excited state contains more of kinetic energy than the same atom in the ground state.
Explanation:
Kinetic energy is the energy acquired by an object due to its motion. And, thermal energy is the internal energy of an object arisen because of the kinetic energy present within the molecules of the object.
Potential energy is the energy acquired by an object due to its position.
The total energy present at the center of mass of an object is known as mass-energy.
So, when an atom gets excited then it means it is gaining kinetic energy due to which it moves from its initial position after getting excited.
Thus, we can conclude that an atom in an excited state contains more of kinetic energy than the same atom in the ground state.
The pressure of Carbon Dioxide in the bottles lower and the CO2 diffuses out from the drink.. Hence bubbles are formed.. :)
