Chem 1100a Tutorial #5 Problems
Note: Where necessary, use the data found in Tables 4.1.1, 4.2.1, and 4.2.3.
1. A sample of gas is compressed by applying pressure to the lid of an insulated container.
What happens to the temperature of the gas? Does the internal energy of the gas increase
2. A dilute solution of HCl with a mass of 610.29 g and containing 0.33183 mol of HCl was
exactly neutralized in a calorimeter by the NaOH in 615.31 g of a comparably dilute
solution. The temperature increased by 3.826 K. The specific heat capacity of the HCl
solution was 4.031 J g °C and that of the NaOH solution was 4.046 J g °C . The heat1
capacity of the calorimeter was 77.99 J °C . What is the heat of neutralization per mole of
HCl? Assume that the original solutions made independent contributions to the total heat
