<h2>Answer:</h2>
The boiling of water in the iron pan is the activity in which both conduction and convention are used.
<h3>Explanation:</h3>
Energy is transferred from one part of the matter to other part in three ways:
- Conduction
- Convection.
- Radiation.
Conduction is the movement of heat from the collision of the microscopic particles in the matter.
While convection is the transfer from the movement of fluids from one place to another.
In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.
Answer:
Expansion and Contraction of underneath or base water
Explanation:
When ice lands on a road, it weakens the soil beneath the pavement, cement by expansion. The slight varying temperatures that leads to the combination of contraction and expansion affects road this leading to potholes on road.
Answer:
Simple squamous epithelium,stratified squamous epithelium,pseudostratified columnar epithelium
Explanation:
The respiratory system is made up of many different types of tissues and they differ according to their locations in the respiratory system.
1.Simple squamous epithelium: It is found within the alveoles of the lungs. These cells are single layer,flat (squamous) cells. It controls the permeability of blood vessels in the lungs. When you inhale it allows more oxygen to be absorbed in the blood flows.
2.stratified squamous epithelium: It is found at mouth surface primarily tongue and throat . These cells are stratified that is they are many layered because everyday whatever we put in our mouth and throat it protects from wear and tear. It gives physical protection from pathogens as well.
3.pseudostratified columnar epithelium: It is a lining of the nasal cavity trachea and bronchi. This layer is ciliary to trap patheogen on entering into the lungs.
