- Question 01:
What can one reasonably expect, when matter made up of particles with relatively high kinetic energies is brought into thermal contact with matter made up of particles with relatively low kinetic energies?
- Question 02:
Samples of neon gas and of krypton gas, with identical numbers of moles, pressures and volumes, are also held at the same temperature. What can be said of the particles of neon gas when compared to the particles of krypton gas?
- Question 03:
A sample of gas is held in a rigid cylinder that has a piston inserted into it.
As the gas expands in the cylinder, the piston is seen to move upwards. Which of the following statements best describes the change that occurs?
- Question 04:
In an exothermic chemical reaction, where the reaction is considered to be ‘the system’;
- Questions 05-06:
A 100.0 g sample of aluminum metal is heated to 80.00°C and then immersed in a relatively cold water bath that contains 0.1000 kg of water until thermal equilibrium is
The specific heat capacity of water is known to be 4.200 J/g°C, and the apparatus is considered to be perfectly insulated (no energy losses are observed to either the
atmosphere or the apparatus itself). The following data are collected.
According to the data, which of the following is the correct set-up for the calculation of the specific heat capacity of Al, if it is assigned a value of x?
- Question 06:
Tin is a metal with a much smaller specific heat capacity than aluminum. If identical samples of tin and aluminum are exposed to identical amounts of energy, which of the following represents the most likely set of observations?
- Question 07:
In a Maxwell-Boltzmann distribution plot of the number of particles of a particular gas (y-axis), and their kinetic energies (x-axis), at three different temperatures, 100K, 200K and 300K, at which temperature will the peak of the curve be furthest to the right on the x-axis?
- Question 08:
When calculating the energy change that occurs when water freezes, which of the following is true?

Which of the following is true, when two bodies at different initial temperature, reach thermal equilibrium after being in thermal contact?
- Question 10:
