An inventor designs a new heat engine that can be modeled on the Carnot cycle. The working gas in the heat engine is 1 mole of helium. The isothermal expansion results in the internal volume changing from 1 L to 3 L. The engine operates at Th = 150 °C and Tc = 25 °C. calculate the volume change associated with adiabatic expansion?
calculate the heat flow for each of the 4 steps?
calculate the work for each of the 4 steps?
calculate the entropy for each of the 4 steps?
calculate the q,wand entropy for the cycle?
Sodium nitrate was added to 2.0 L of water at 25 °C to produce a saturated solution. The solution was then heated to 80 °C. Calculate the mass of lead nitrate that had to be added to produce a saturated solution at that higher temperature.
Calculate the volume of concentrated reagent required to prepare the diluted solutions indicated.
Adipic acid and citric acid have very similar melting points. Given two unkown samples, one being citric and the other adipic acid
A calorimeter contains 27.0 mL of water at 11.0 C. When 2.10 g of X (a substance with a molar mass of 74.0 g/mol) is added, it dissolves via the reaction X{(s)}+H_2O{(l)} -> X{(aq)}
