What isothermal process?
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
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.
Example of isothermal process?
An isothermal process is a change in a system where the temperature stays constant (delta T =0). A practical example of this is some heat engines which work on the basis of the carnot cycle. The carnot cycle works on the basis of isothermal.
What is mean by isothermal in gas chromatography?
It means that you keep the temperature constant during the entire run
When temperature and number of particles of a gas are constant what is also constant?
The product of pressure and volume. Does PV = nRT look familiar? (:

What is mean by non isothermal columns?
isothermal means 'constant temperature' so to be non-isothermal means to have non-constant temperature.
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.

In GC isothermal is when the temperature is constant but what is it called when the temperature is programmed to increase?
Programmed temperature.
Where does the temperature stay constant with increasing altitude?
Isothermal layer
What statement best describe the isothermal process?
The temperature remains constant
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.
In Gas Chromatography isothermal is when the temperature is constant but what is it called when the temperature is programmed to increase?
Temperature Programming (from what i learned in Quantitative Analysis)
