Explanation:
if this helps please follow me
I don't know in how many words we have to write so if this is short please tell me
Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.
Basic science concepts behind few daily applications of science
Cooking:
Heat energy is transformed to the cooking vessel in the form of radiation, conduction and convection. After the heat energy is passed the various ingredients like, salt, sugar or any edible material starts breaking bonds and forms new bonds which gives us delicious food. Therefore, physics as well as chemistry is involved. In order to prepare the perfect delicacy, the perfect proportions of the ingredients are very important. Hence maths plays a major role too
Vehicles:
The fuel in the vehicles are burnt in order for the vehicle to get energy. The concept involved in the burning of the fuel is combustion. The conversion of heat energy into electrical energy and mechanical energy takes place. Hence chemistry and physics are involved.
Mixer / Juicer:It converts the electrical energy into mechanical energy. It uses the principle of centrifugal force.
Refrigerator:
Electrical energy is converted to heat energy where cooling takes place.
AC(Air Conditioner):
It keeps us cool in summers.
There are so many other such fascinating applications of science, where simple and basic science concepts are the underlying principles
