What is the formula for specific heat capacity? 10.0 g of jet fuel is burned in a calorimeter containing 200 mL of water. The temperature of water increases from 15.0 deg C to 55.0 deg C. Calculate the total heat produced (in J) and the heat of combustion (in J/g) of the jet fuel...
Gibbs Free Energy, denoted as G, is a thermodynamic quantity used to predict the spontaneity of a process at constant pressure and temperature. It incorporates enthalpy (H), temperature (T), and entropy (S) of the system, described by the formula G=H−TS. On the other hand, Standard ...
Tetraethyl orthosilicate (TEOS) is the chemical compound with the formula Si(OC2H5)4, and it is a colorless liquid that degrades in water. TEOS molecule consists of four ethyl groups attached to SiO4- ion, which is called orthosilicate. As an ion in solution, orthosilicate does not exist....
So, hydration of cement is chemical reaction of cement with water molecules in an exothermic process. The heat of hydration of cement is the amount of energy required to hydrate a mass unit of cement (1 kg) in water at 37°C. This quantity is defined as the product of the enthalpy chan...
Scientists use the term 'change in enthalpy' to describe a gain or loss in energy by a compound or reaction. If the pressure is kept constant, the change in enthalpy can be generally thought of as a change in heat. When a liquid is cooled, it has a negative change in enthalpy; it ...
Why is the volume formula for a cone one-third that of a cylinder? The volume formula for a cone is one-third that of a cylinder with the same base and height because geometrically, a cone can be thought of as having one-third the volume of a cylinder, a concept proven through calcul...
