Why impulse sampling is impracticable?
it is impracticable because the time period of sampled impulse is 0 i.e t=0 and in real life it is impossible to produce a signal of 0sec.
What does a sudden burst of cycle tire represent the opsions are 1.isothermal 2.isobaric 3.adiabatic?
adiabatic
Derivation for workdone in isothermal process?
In thermodynamics, an adiabatic process or an isocaloric process is a process in which no heat is transferred to or from working fluid. The term "adiabatic" literally means an absence of heat transfer; for example, an adiabatic boundary is a boundary that is impermeable to heat transfer and the system is said to be adiabatically (or thermally) insulated. An insulated wall approximates an adiabatic boundary. Another example is the adiabatic flame temperature, which is the temperature that would be achieved by a flame in the absence of heat loss to the surroundings. An adiabatic process which is also reversible is called an isotropic process.Ideal gas:For a simple substance, during an adiabatic process in which the volume increases, the internal energy of the working substance must necessarily decrease. The mathematical equation for an ideal fluid undergoing an adiabatic process is,p.v^( γ )where P is pressure, V is volume, andγ =CP/CV=α +1 / α .CP being the molar specific heat for constant pressure and CV being the molar specific heat for constant volume. α comes from the number of degrees of freedom divided by 2 (3/2 for monotonic gas, 5/2 for diatomic gas). For a monotonic ideal gas, γ = 5 / 3, and for a diatomic gas (such as nitrogen and oxygen, the main components of air) γ = 7 / 5. Note that the above formula is only applicable to classical ideal gases and not Bose-Einstein or Fermi gases.For the derivation of work done in an adiabatic process, please visit the link I added below.
Are all your answer's right?
I think that 95% of are answers are right,other 5% can be change by other peopole.
How do you draw an abiatic line on a graph?
That depends on what you have chosen for the axes. If one of the axes is enthalpy, then an adiabatic line would be a straight line perpendicular to that axis.
A change in temperature without an accompanying change in the amount of heat present is called what?
It is called adiabatic or an adiabatic process.
What is the rate of adiabatic temperature change in saturated air?
As I recall from flight school, the adiabatic lapse rate is 4.5oF per 1000 feet.
Why ferromagnetic substances are not used in adiabatic demagnetization?
A system that is a perfect ferromagnet has all the spins aligned whether or not there is an external magnetic field. As a result applying an external magentic field does not change the spin configuration at all, and does not change the entropy at all. Therefore this will not change the temperature.
When air expands of contracts what type of temperature change does it experience?
adiabatic
What is a adiabatic purpose?
I'll assume the last word was 'process'. Adiabatic processes are those that proceed without the temperature changing, whilst the pressure and volume do change. For practical purposes, sound waves passing through the air are adiabatic.
What is adiabatic and diathermal wall?
the temperature that is within the system closed by adiabatic wall is called adiabatic wall temperature
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 an adiabotic process?
A change in pressure and volume of a gas when no heat is allowed to enter or escape from the gas is called adiabatic change . For an adiabatic change , the exchange of heat between the gas and the surroundings must be preserved. So the walls of container must be perfectly non conducting.
What is an adiabat?
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
What describes a process that occurs without a change in pressure?
A process that has no transfer of heat is usually referred to as "adiabatic".
What is a sentence using the word impracticable?
Most of the plans to raise the Titanic were impracticable due to the great depth of the ocean.
Adiabatic processes cause cooling by?
Adiabatic cools by decompression.
