Answer:
a) water molecules move rapidly in the mug of boiling water while they move slowly in the ice water. In the ice itself, the molecules stay in place.
b) Water must release energy to move from a higher to lower energy phase, i.e., from gas (water) vapor to liquid during condensation and from liquid to solid (ice) during freezing. In each case, the energy released by the water results in a change in the internal molecular bonding structure.
Explanation:
Because while doing research scientist follow the scientific metod.The scientific method involves exploration and observation and the search for the answer for a question. And there will always some hypotesis that while experimenting reveal to be wrong.
Answer:
A. the electric motor
Explanation:
A cell is a biological molecule which is the basic and functional unit of life. Cells undergo series of processes to function appropriately. ATP is an acronym for adenosine triphosphate, which is the source of energy for various cell processes.
In the given mechanical system, the electric motor provides the energy required energy to drive the system. Therefore, the electric motor has the same major function of providing energy for the system as the ATP in a cell.
Mass spectrometry was discovered by Francis Aston, a British Physicist, in 1919. This involves separating mixtures of substances into their components and transforming them into beams of particles and subsequently, bending them with the use of electricity and magnetism to come up with a spectrum that is inherently unique for every individual atoms for easy identification.
