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!
An isothermal process is the change of a system. But in this system the temperature still remains constant.
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.
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
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.
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 wall is the one from which no energy transfer takes place. diathermic wall give the facility of transfer of energy between two bodies.
"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).
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.
Isothermal process is a process in which change in pressure and volume takes place at a constant temperature.
Air that is rising at the dry adiabatic rate can simply cool at the rate at which the decreasing pressure forces it to. Once it cools to its dew point at the lifting condensat…ion level, it must condense some of its moisture in order to cool anymore (it is already saturated at this point). Condensation is a process that releases latent heat into the atmosphere, warming the air. Therefore, this heat released counteracts some of the adiabatic cooling that continues to take place as the air rises, and the net effect is a rate of cooling that is reduced. This is the saturated (or moist) adiabatic lapse rate.
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.
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 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.
Full annealing process consists of three steps. First step is heating the steel component to above upper critical temperature by 30 to 50 deg c, after suffciant soaking time p…arts will be cooled very slowly in the furnace. Where as for ISo Thermal annealing parts will be heated above upper critical temperature by 30 to 50 deg c, after suffciant soaking time parts will be transfered to intermediate temprature( Below the lower critical temperature) and allow to equalise the temperature then cool in air to Room temperature
isobars are lines of equal pressure , isotherms are line of equal temperature that's the difference this is by jenisea phoenix lol smile face
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.
