Where does the temperature stay constant with increasing altitude?
Isothermal layer
How ice is isothermal?
yes it is an isothermal process because the temperature remains constant while the ice changes its state from solid to liquid.
What is isothermal?
uhnn. cold, hard.and long
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.
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).
In GC isothermal is when the temperature is constant but what is it called when the temperature is programmed to increase?
Programmed temperature.
What is mean by isothermal in gas chromatography?
It means that you keep the temperature constant during the entire run
What is mean by non isothermal columns?
isothermal means 'constant temperature' so to be non-isothermal means to have non-constant temperature.
What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
Where does the temperature stay constant with increasing altitude?
Isothermal layer
What statement best describe the isothermal process?
The temperature remains constant
Which of the following is true of an isothermal process Temperature is constant W equals Q ΔU equals 0 Pressure is constant?
Temperature is constant.
What is true about isothermal process?
An isothermal process is one which does not take in or give off heat; it is perfectly insulated. Iso = same, thermal = heat. In real life there are very few isothermal processes. Heat loss accounts for most process inefficiencies.
Define isothermal expansion?
Isothermal expansion is what keeps gas at a constant temperature. It works by absorbing heat in order to conserve energy.
How ice is isothermal?
yes it is an isothermal process because the temperature remains constant while the ice changes its state from solid to liquid.
What is isothermal?

How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
