The purpose of a gasoline car engine is to convert gasoline into motion
so that your car can move. Currently the easiest way to create motion
from gasoline is to burn the gasoline inside an engine.
Therefore, a car engine is an internal combustion engine -- combustion takes place internally.
There is such a thing as an external combustion engine. A steam engine
in old-fashioned trains and steam boats is the best example of an
external combustion engine. The fuel (coal, wood, oil, whatever) in a
steam engine burns outside the engine to create steam, and the steam
creates motion inside the engine. Internal combustion is a lot more
efficient (takes less fuel per mile) than external combustion, plus an
internal combustion engine is a lot smaller than an equivalent external
combustion engine. This explains why we don't see any cars using steam
engines.
To understand the basic idea behind how a reciprocating internal
combustion engine works, it is helpful to have a good mental image of
how "internal combustion" works.
One good example is an old Revolutionary War cannon. You have probably
seen these in movies, where the soldiers load the cannon with gun powder
and a cannon ball and light it. That is internal combustion, but it is
hard to imagine that having anything to do with engines.
A potato cannon uses the basic principle behind any reciprocating
internal combustion engine: If you put a tiny amount of high-energy fuel
(like gasoline) in a small, enclosed space and ignite it, an incredible
amount of energy is released in the form of expanding gas. You can use
that energy to propel a potato 500 feet. In this case, the energy is
translated into potato motion. You can also use it for more interesting
purposes. For example, if you can create a cycle that allows you to set
off explosions like this hundreds of times per minute, and if you can
harness that energy in a useful way, what you have is the core of a car
engine! </span>
Answer:d
Explanation:1 times 1.63 times 2
Answer:
The value is
Explanation:
From the question we are told that
The volume is
The initial pressure is
The initial temperature is
The final temperature is
Generally for an adiabatic process the workdone is mathematically represented as
Here is the internal energy of the system which is mathematically represented as
So
Generally from ideal gas equation we have that
Here R is the gas constant with value
So
=>
So
=>
Answer:
The acceleration of a rock thrown straight upward on the way up, at the top of its flight and on the way down is called gravity, and it's denoted by the letter g.
Gravity change vary depending on the position on Earth or the planet that you are studying
Usually on earth we use
Explanation:
<u>If we analyze </u><u>Newton's second law</u>
<u>Then we have the force that is caused by the </u><u>weight</u><u> of the rock</u>
So, we have that
