Answer:
Pressure (P) is the amount of force applied perpendicular to the surface of an object per unit area. The SI unit of pressure is the pascal (Pa), which is equivalent to N/
(newtons per meter squared).
Answer: Either electromagnetic radiation or energy is the answer to your question.
Yes. It is rather a natural phenomenon. If you search and understand the process of chemical
change or reaction that results to its chemical property outcome, it has a new
formed substance. Unlike physical change or reaction it only changes in shape
or form but the substance, compound or element in the matter is till the same.
Furthermore, when chemical change is undergoing you notice the change in shape,
size and from like the physical change but there is a change in the element,
compound or substance. When you lit a fire on a paper the fire disorients,
disorganizes and disturb the former positions of the atoms and because of the
fire as catalyzer the atoms did its behavior –changing both intrinsic and extrinsic.
Answer:
The<u> heat transfer </u>model showed convection.
In the convection model, the red water on the bottom of the beaker <u>is hot</u>
This means that the water at the bottom of the beaker was <u> less dense than </u>the water near the top of the beaker.
Explanation:
<em>Convection</em> is the transference of heat energy by the movement (translation) of the particles of fluid (liquids or gases).
When the water on the bottom of the beaker is heated, it expands and becomes less dense.
The water near the top of the beaker is cold which makes it denser than the water at the bottom of the beaker.
Thus, the hot water from the bottom of the beaker will ascend toward the top of the beaker, while the cold water on top will descend toward the bottom. As long, as there is a difference of temperature between the water on the bottom and on top of the beaker, there will be a continuous movement of the particles: cold particles from the top replace hot particles from the bottom that ascend, and when the cold particles are heated they will ascend and will be replaced by new cold particles. This continuous translation of hot and cold particles in fluids is the model of heat transfer by convection.
