Heat is energy and work is done by means of energy !

For suppose I have to push the box towards right and for pushing it I have to apply force but I will apply force only if I have energy !

So work and energy are related to each other by means of force .

Work can also be defined as product of force and displacement .

Work = Force × displacement

And work increases if force and displacement both are increased.

matters are made up of atoms. Then ask the next question, "What are atoms?"

Atoms are the smallest part of an element. They are composed of nucleus and electrons, electrons surround nucleus. Elements are identified by the number of electrons in orbit around nucleus of atoms and by the number of protons in nucleus.

Understanding Electricity - What is electricity?, Current, Voltage and Resistance, How to measure current, voltage and resistance, How electricity works

Nucleus is made up of protons and neutrons, and the number of protons and neutrons are balanced. Neutrons have no electric charge, protons have positive charges (+) and electrons have negative charges (-). A positive charge of proton equals a negative charge of electron.

Electrons are bound in their orbit by attraction of protons, but electrons in the outer band can become free of their orbit by some external forces. These are referred to as free electrons, which move from one atom to the next, electron flows are produced. These are the basis of electricity. Materials that allow many electrons to move freely are called conductors and materials that allow few free electrons to move are called insulators.

All matters are made up of atoms that have electric charges. Therefore, they have electric charges. For the matter that has a balanced the number of protons and electrons, positive charge force and negative charge force are balanced. It is called neutral state of an atom. (The number of protons and electrons remains equal.)

Nervous and hormonal system together perform the function of control and coordination in human beings. justify the statement. nervous and hormonal system together perform the function of control and coordination in human beings. let us take an example, in the case of any emergency, stimulus is being perceived by cns (nervous system). the stimulus is analysed and the response is sent to the effectors. simultaneously, sympathetic nerves stimulate adrenal gland to release adrenaline which regulates blood pressure, increases heartbeat, constricts blood vessels and dilates pupil, etc. so, both nervous and endocrine systems interact and overcome the crisis together.
