How much heat does pure benzene need to absorb as its temperature rises from 100 degrees to 150 degrees?

Please provide the detailed calculation process. Thank you~
Just look up chemical thermodynamics or physical chemistry. The general heat calculation in chemical processes is essentially a calculation of enthalpy; one needs to find the enthalpy value of pure benzene at 150 degrees (the pressure must also be known), and then subtract that from the enthalpy value of benzene at the same temperature and pressure. By the way, it’s also necessary to know the flow rate of pure benzene. What is usually available is the enthalpy value per mole of benzene, so the flow rate you have to convert into a molar flow rate.
It should be 100 degrees later on, sorry
