Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.
What is adiabatic cooling?
Adiabatic cooling is cooling that occurs without removing any energy from the system. It often occurs when a gas is decompressed. Adiabatic heating and cooling play an important role in weather.
When does expansion occur?
Expansion occurs when there is a change in volume due to increased temperature. Contraction occurs when there is a decrease in volume due to decreased temperature.
Why compression and combustion are always adiabatic process?
Adiabatic compression occurs when a precisely controlled mixture of a flammable gas and oxygen are ignited by the heat of colliding molecules during the compression of said gas. This causes an explosion and the explosion causes an expansion of the gasses. These expanding gasses must force their way out of confinement and pushes a piston. This turns tirns a crank shaft which will mechanically open and close intake and exhaust valves through push rods.
Is melting process is adiabatic process?
An adiabatic process in the opposite of a diabatic process. The adiabatic process occurs without the exchange of heat with its environment. A diabatic process exchanges heat with the environment.
Why does expansion happen?
Expansion occurs when a substance is heated. The energy given to the molecules in the substance causes them to vibrate and so they get pushed further apart, causing the substance to expand.
What happens to atoms and molecules when a chemical change occurs?
They get rearranged to form new products.
Explain the Difference between adiabatic and isothermal compression?
"Adiabatic process" refers to processes that take place in a closed system with no heat interaction with it's surroundings. "Isentropic process" refers to processes that take place in a closed system with no heat interaction with the surroundings (adiabatic process) and internally reversible. This is, no internal generation of entropy, entropy stays constant, which is what is meant by "isentropic". We can also say, an isentropic process is one where entropy stays constant, and no heat interaction of the system with the surroundings takes place (adiabatic process). Or, an adiabatic process can be irreversible, or reversible (isentropic).
What is equilibrium with respect to movement of molecules across a cell membrane?
that happens when osmosis occurs
What is the rate of cooling as you increase in elevation?
The rate at which adiabatic cooling occurs with increasing altitude for wet air (air containing clouds or other visible forms of moisture) is called the wet adiabatic lapse rate, the moist adiabatic lapse rate, or the saturated adiabatic lapse rate.
What is adiabatic heating and cooling?
Adiabatic cooling happens as air mass expands with increasing elevation (because density of gases decreases farther into the atmosphere). As elevation increases, the air gets cooler because energy is drawn from the surroundings. Less dense air traps less heat resulting in this net cooling called adiabatic cooling. It occurs at an average of 6 degrees Celsius per 1000 meters, but it can vary.
When air rises does it expand and cool adiabatically?
Yes. Adiabatic cooling occurs when there is a change in only pressure.
