Simplify the energy balance equation for eavch of the following cases. State whether Q or W is positive, negative or zero in each case. Clearly state your choice of system. a. Water in a lake falls 200 meters through a 6 inch diameter pipe and exits into a river System = ____________ b. Acetic acid flows through tubes of a furance, where it reacts to ketene and water. System =______ c. Cold milk is added to a hot cup of coffee. System = Also, I need to Know in EACH CASE please the following 1-if (delta potential energy) and/or (delta Kinetic energy) is zero or not ? 2-if the system is (open system) or (closed system)? would truly appreciate If someone can explain since I'm confused also when to use (delta U) and (delta H) ?
