"Propels" Natural Recordings by Native Speakers
Propels: to push or drive something or someone forward, typically with great force or speed.
In Greek grammar, a proparoxytone is a type of word or phrase that is stressed on the third to last syllable. This is in contrast to an oxytone, which is stressed on the final syllable, and a paroxytone, which is stressed on the second to last syllable.
To propel means to push or drive something forward with force, often making it move or progress suddenly and quickly. It can also mean to give someone a strong emotional or motivational push to do something. For example: "The coach's words propelled me to win the game."
A substance used to produce a propulsive force to drive a vehicle, such as a rocket, through space or to generate thrust in an aircraft.
Propellants are substances that are used to generate thrust or propulsive force, typically in rockets, engines, or other propulsion systems. They work by generating a high-pressure gas that is expelled out of a nozzle, producing a forward force or thrust.<br><br>In a more general sense, propellants can also refer to substances that are used to make something move or propel it forward. For example, a propellant in a firework is a substance that produces a high-pressure gas when it burns, causing the firework to lift off the ground.<br><br>Examples of propellants include:<br><br> Liquid fuels (e.g. liquid hydrogen, liquid oxygen) used in rocket engines<br> Solid fuels (e.g. ammonium perchlorate) used in solid rocket boosters<br> Compressed gases (e.g. compressed air, compressed nitrogen) used in pneumatic systems<br> Explosives (e.g. nitroglycerin) used in some rocket propellants and other applications.<br><br>The choice of propellant depends on the specific application and the desired performance characteristics of the system.
A rotating wing-like device used to propel something, typically an aircraft or a boat, through the air or water.
Propellers are spiral-shaped blades or vanes attached to a central axis, typically made of metal, wood, or composite materials, used to convert rotary motion into thrust or propulsion. They are commonly found on aircraft, boats, helicopters, and wind turbines, and are used to generate lift, thrust, or to harness wind energy.
To move (something or someone) forward with force or impetus, typically by pushing or imparting motion to it with a propelling force, such as a jet of gas, steam, or water, or an explosive charge or propeller.<br><br>Example sentences:<br> The spacecraft used its rocket to propelling upward into orbit.<br> The propelling force of the engine made the car accelerate rapidly.<br> The propelling device used to launch the golf ball into the air.
Propene, also known as propylene, is an organic chemical compound that is the simplest unsaturated hydrocarbon, having the chemical formula C3H6. It is a colorless, flammable gas with a boiling point of -48.2°C and a melting point of -185.5°C.<br><br>Propene is an important building block for the production of various chemicals, including plastics, polymers, and rubbers. It is also used as a fuel and as an intermediate in the production of various other chemicals.<br><br>Propene is also known as propylene, propene-1, and methyl ethylene.
The noun "propensity" refers to a natural or habitual tendency or inclination towards something, often used to describe a characteristic or attitude that is typical of a person, a group, or a situation.<br><br>Example sentences:<br><br> She has a propensity for sarcasm, often making witty remarks at social gatherings.<br> The company has a propensity for innovation, investing in new technologies and ideas.<br> He has a propensity for taking risks and trying new things.<br><br>In positive contexts, propensity can imply a talent or aptitude for something, while in negative contexts, it can suggest a tendency towards a bad habit or behavior.<br><br>Synonyms for propensity include: inclination, tendency, predisposition, bent, and bias.
A propenyl group is a functional group that is a type of alkyl group. It is derived from a propylene molecule (C3H6) and consists of three carbon atoms connected in a chain.<br><br>The propenyl group is denoted by the symbol -CH2CHCH₂.<br><br>It is a vinyl group (a carbon-carbon double bond) attached to a methyl group (-CH₃), and it is often used in organic chemistry to indicate the presence of a double bond in a carbon chain.
