Thread Content

Hello friends! 1) Could you please tell me about the heat of vaporization and function values ​​of water vapor and water under different pressures. unit: Kilojoules per kilogram 2) Is there any way to check the heat capacity at constant pressure and heat capacity at constant volume of a substance? (There is a way in the book to calculate the constant volume heat capacity of a substance C=a+b * t+c * t^2, Unfortunately, the types of substances listed in the book are too few and I don’t need them. However, there are documents in the book that can be found, so I would like to ask friends for help! ) Urgent
