Distinguish among specific heat capacity, molar heat capacity, and heat capacity.
An adiabatic process is one that involves no heat transfer. What is the relationship between work and the change in internal energy in an adiabatic process?
Classify the following processes as exothermic or endothermic: (a) freezing of water; (b) boiling of water; (c) digestion of food; (d) a person running; (e) a person growing; (f) wood being chopped; (g) heating with a furnace.
When \(1 \mathrm{~mol}\) of \(\mathrm{KBr}(s)\) decomposes to its elements, \(394 \mathrm{~kJ}\) of heat is absorbed. (a) Write a balanced thermochemical equation. (b) What is \(\Delta H\) when \(10.0 \mathrm{~kg}\) of \(\mathrm{KBr}\) forms from its elements?
Liquid hydrogen peroxide, an oxidizing agent in many rocket fuel mixtures, releases oxygen gas on decomposition: $$2 \mathrm{H}_{2} \mathrm{O}_{2}(l) \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(l)+\mathrm{O}_{2}(g) \quad \Delta H=-196.1 \mathrm{~kJ}$$ How much heat is released when \(652 \mathrm{~kg}\) of \(\mathrm{H}_{2} \mathrm{O}_{2}\) decomposes?
