Geometry The volume V of a right circular cone varies jointly with the square of its radius r and its height h. The 1T constant of proportionality is -. See the figure. Write an equation for V. 3 I h 1

And that is called the change of enthalpy. To measure enthalpy we use calorimeter mostly it is best for fast reactions. Procedures: First we need to measure the heat capacity of the calorimeter Measure the temperature of cool water Measure the temperature for hot water Pour them into each other Measure the final temperature Do this for 2 more trial Enthalpy of neutralization Measure the temp of 50 ML HCL Record the temperature of 50 mL NaOH Pour them into the calorimeter Record the final temp Do it for 2 more trails Diss
