How do you calculate heat of combustion?
How do you calculate heat of combustion? The heat of combustion is calculated by multiplying the mass of the water times the specific heat of the water times the change in temperature. This entire equation is multiplied by -1, because heat of combustion is negative because heat is being lost or released. What is combustion […]
