Answer:
Explanation:
At room temperature the thickness of the film is just enough that it will cancel the reflected light
So here we will have
so we have
here we have
now we have
now when temperature is increased to 177 degree C
then in this case we have
now we have
now we know by the formula of thermal expansion
Explanation:
"When a solution reaches the point where it cannot dissolve any more solute it is considered "saturated." If a saturated solution loses some solvent, then solid crystals of the solute will start to form. This is what happens when water evaporates and salt crystals begin to form."
Answer:
Explanation:
The three things that occur naturally everyday and how science has had an impact on what we think or do about them is
Photosynthesis is a process in which green plants manufacture there own food in the presence of sunlight through the equation below
6CO₂ + 6H₂O ⇒ C₆H₁₂O₆ + 6O₂
From the equation above, it can be seen that aside from the food (C₆H₁₂O₆) produced by green plants during photosynthesis, science has assisted us in knowing that these green plants take-up the carbon dioxide (CO₂) that is exhaled by humans and release the oxygen (O₂) that is inhaled by humans thereby purifying the air of the surrounding they are found. This concept has made man understand the importance of planting in residential areas.
Depletion of the Ozone layer; the ozone layer is a layer in the earth stratosphere which shields the earth from direct sunlight/rays. Over the years, the burning of hydrocarbon on earth has caused the depletion of this layer thereby exposing the earth to more direct sunlight from the sun. Science has had an impact in the thinking of man in this regard by making us more conscious of the risk of burning these hydrocarbons which has led to the collective efforts by governments across the world to minimize the burning of these substances.
Rain; rain are droplets of water that fall from the atmosphere. Rain formation occurs when water (in the form of ocean, river and/or seas) are evaporated into the atmosphere as a result of heat from the sun. These evaporated water molecule rises and cools down to form and form a cloud It is then returned to earth in the form of rain. This explanation changes the mythical understanding of rain in different culture
