What else can I help you with?
In Gas Chromatography isothermal is when the temperature is constant but what is it called when the temperature is programmed to increase?
When the temperature is programmed to increase in Gas Chromatography, it is called temperature programming or temperature ramping. This technique involves gradually increasing the temperature during the analysis to separate compounds based on their boiling points and improve resolution.
What is isothermal?
uhnn. cold, hard.and long
Where does the temperature stay constant with increasing altitude?
In the stratosphere, the temperature generally remains constant or may even slightly increase with increasing altitude. This is due to the absorption of ultraviolet radiation by the ozone layer, which warms the stratosphere.
Difference between isothermal and isobaric heating of saturated steam?
Isothermal heating of saturated steam occurs at constant temperature, while isobaric heating occurs at constant pressure. During isothermal heating, the temperature of the steam remains constant as it absorbs heat energy and undergoes a phase change. In contrast, during isobaric heating, the pressure remains constant as the steam absorbs heat energy, leading to an increase in temperature while remaining in the vapor state.
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 are the condition for ideal fluid?
1.Isothermal expansion at a high temperature AB 2.Adiabatic expansion as the temperature falls to a lower rule BC 3.Isothermal compression at lower temperature CD 4.Adiabatic compression as temperature increase to initial high volume DA
Is isothermal expansion reversible under ideal conditions?
No. All processes involving heat transfer are not reversible, since they result in an increase in entropy. Isothermal expansion implies heat transfer to maintain the system at a constant temperature. Normally an expanding gas would cool if there were no heat entering the system. Adiabatic processes involve no heat transfer and are reversible. The temperature can (and usually does) change during an adiabatic process.
When does raising the temperature of a gas increase its preasure?
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
When the temperature of a gas is constant will the volume increase or decrease as the pressure decreases?
When the temperature of a gas is constant and the pressure decreases, the volume will increase. This is described by Boyle's Law, which states that at constant temperature, the pressure and volume of a gas are inversely proportional to each other.
How will volume of a balloon change if pressure remains constant but temperature increases?
The volume will increase in proportion to the increase in absolute temperature.
What happens to the temperature increase the number of particles what happens to the pressure?
Increasing the temperature the number of particles remain constant and the pressure increase.
What is the temperature if the gas pressure is constant?
At isobaric (pressure) expansion (volume increase) the temperature will increase because V is proportional to T for the same amount of gas (closed container) at constant pressure.
