Direction: Write F if the statement is correct and B if it is incorrect. ________1. According to the first law of thermodynamics, energy can be created and destroyed. ________2. The energy of the surroundings is called as internal energy. ________3. Internal energy of the system is composed of two state functions called heat and work. ________4. When both q and w are both positive, the internal energy of the system increases. ________5. The work done by the system is categorized by a negative (-) sign on the value of work (w). ________6. Enthalpy is symbolized by the letter H which refers to the energy transferred under constant temperature. ________7. At constant pressure, change in enthalpy is always equal to heat (q). ________8. An exothermic reaction feels cold to the touch because heat is absorbed by the system. ________9. When the heat energy of product is greater than its reactant, it is categorized by an endothermic reaction. ________10. Thermochemical equation shows the enthalpy relationships between reactants and products.
