Difference between isothermal and adiabatic process?
Isothermal process is going on under constant temperature, adiabatic is a process where no heat is exchanged (this does not imply that temperature is constant).

Thanks for the feedback!
The process in which change in pressure ,volume and temperature takes place without any heat entering or leaving the system is called an adiabatic process
An adiabatic compressor does not exchange heat with its surroundings so the temperature of the compressed material will increase, in an isothermal compressor the materia…l's temperature is kept constant by expelling heat to it's surroundings.
isobars are lines that connect areas of the same air pressure drawn on a weather map. Isotherms are lines that connect points having same temperature on a weather map.
Adiabatic means without any transfer of heat, and isothermal means having only one constant temperature.
An isothermal process is the change of a system. But in this system the temperature still remains constant.
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
Isobars are lines of equal pressure, isotherms are lines of equal temperature. And isobars are pretty and gorgeous, and isotherms are thermometers.
isobars are lines of equal pressure , isotherms are line of equal temperature that's the difference this is by jenisea phoenix lol smile face
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.
ISOTHERMAL PROCESS: in this the temperature is maintain as constant. (T=C) ADIABATIC PROCESS: there is no heat transfer from the system to surrounding.
Adiabatic expansion is an increase in volume while pressure is maintained constant. When this occurs, temperature also increases. Isothermal expansion is an increase i…n volume while temperature is maintained constant. When this occurs, pressure decreases.
An isothermal calorimeter is a tool used to bind small molecules to larger macromolecules, and determine the thermodynamic parameters of interactions in a solution. An iso…peribol calorimeter measures the heat created by a sample burned under an oxygen atmosphere in a closed vessel surrounded by water, in controlled conditions. The measurement is known as a BTU value.
Environment lapse rate is nothing but rate of reduction/decrease with height for an atmospheric variable, mostly temprature is considered. It will not sound good, if we don'…t discuss it mathematically, r = - dT/dH , which can be phrased as negative of the rate of change of temprature with change in altitude. T =Temprature, H = Height Of course there are two types of lapse rate 1.Environmental lapse rate - This actually refers to the actual change of temperature with altitude for the stationary atmosphere (i.e. the temperature gradient) The environmental lapse rate also represented as ELR, is the rate of reduction of temperature with height in the stationary atmosphere at a given time and location. 2.The adiabatic lapse rate - This refer to the change in temperature of a mass of air as it moves upwards. Further there are two adiabatic rates: a.Dry adiabatic lapse rate The dry adiabatic lapse rate also shorted as DALR is the rate of temperature decrease with height for a parcel of dry or unsaturated air rising under adiabatic conditions. b.Moist/saturated adiabatic lapse rate This applies when the air is saturated with water vapor at said dew point also shorted as MALR or saturated adiabatic lapse rate - SALR. The following are the key differences: Environmental Lapse rate is change of temperature with altitute for a stable atmosphere where as adiabatic lapse rates is the change in temperature of a mass of air as it moves upwards.
"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 ta…ke 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).
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even… in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.
An isothremal process is one in which the temperature is constant. heat can be gained or lost in order to maintain a constant tempereature. An adiabatic process is one in whic…h there is no heat exchange between a system and its surroundings. It does not matter whether the temperature of the system is constant or not.
