Iam realy doubt on adiabatic process bcz we all know that heat is flow from lower temperature to higher temprature that is heat depends on temprature diffrence. So at constant temprture the heat will become constant. But in the case of adiabatic process the heat is constant but temprature is not constant why? Plz... Reply

Hi, I know this is three months later, but hopefully this answers your question. Heat is not temperature. Heat is a form of energy, temperature is a measure of hotness in a body. they have different measurements, different parameters. Therefor heat and can increase/decrease without temperature increase or decrease. This is seen as we heat water. Water boils at 100C, so adding heat until boiling temperature increases the heat, but at phase changes, temperature DOES NOT CHANGE. This is known as latent heat, i.e. the heat required to change heat from one phase to another. This is because heat is required to break the bonds, and the heat is not used to increase the temperature. For this reason, temperature can change due to heat, but are not always dependant on one another. heat=mass*specific heat capacity*difference in temperature, which means you can add heat by increasing the amount of the substance you have, even if temperature of the bodies are the same. Don't let this formula confuse you, as latent heat has its own formula as latent heat=specific latent heat of (vaporisation or fusion)*mass. Maybe you have figured by now, that for this reason adiabatic processes and isothermal processes are not the same. Isothermal the temperature remains constant, adiabatic the heat of the system remains constant. That means isothermal processes can have phase changes, where heat is added or removed. Adiabatic processes can't have phase changes as heat cannot enter or exit the system therefor changing the phase. In short your statement "So at constant temperature the heat will become constant", is incorrect, as temperature and heat have different parameters, as they measure different quantities, and can change somewhat independently. I hope this answers your question!

why adiabatic is pv^r=k?

@antoineohalloran8724 thanks a lot . Had the same doubt. Intact one of my friends tried to explain this to me when walking back to class. But this is really understood ❤❤
