Which is an example of propellant?
Common propellants are energetic materials and consist of a fuel like gasoline, jet fuel, rocket fuel, and an oxidizer. Propellants are burned or otherwise decomposed to produce the propellant gas. Other propellants are simply liquids that can readily be vaporized.
What is a propellant What does it do?
A propellant is a material that is used to move an object by applying a motive force. This may or may not involve a chemical reaction. It may be a gas, liquid, plasma, or, before the chemical reaction, a solid. Common chemical propellants consist of a fuel, like gasoline, jet fuel and rocket fuel, and an oxidizer.
What are the two types of propellant?
Most liquid chemical rockets use two separate propellants: a fuel and an oxidizer.
What is propellant made of?
PROPELLANT TYPES AND PROPERTIES Solid propellants are made up of three basic ingredients: Page 5 • oxidizer, • fuel, and • binder. Two, or even three, of these may be contained in the same material. Nitrocellulose is an example of all three, when colloided.
Is propellant harmful?
Ventricular tachyarrhythmias, bradyarrhythmias, acute heart failure, arterial hypotension, and asphyxia may cause sudden death in youths who deliberately inhale aerosol propellants. The possibility that these gases are harmful, acutely or chronically, to frequent aerosol users requires further study.

Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus. Sense organs contain groups of receptors that respond to specific stimuli.
How does a stimulus reach the brain?

Your emotions, decisions, and physical actions all happen through nerve impulses traveling through neurons in your brain, spinal cord and nerves.
How the brain processes an external stimulus?
The brain is a part of the central nervous system that is in charge of higher cognitive functions. It facilitates sending instructions to our effector organs such as muscles and glands and it also processes sensory information we receive from the environment that is any external stimulus.
What is internal and external stimulus?
An external stimulus is a stimulus that comes from outside an organism and causes a reaction. An internal stimulus is a stimulus that comes from inside an organism.
