In a physics lab students are conducting an experiment to learn about the heat capacity of different materials. The first group is instructed to add 1.5-g copper pellets at a temperature of 92°C to 345 g of water at 16°C. A second group is given the same number of 1.5-g pellets as the first group, but these are now aluminum pellets. Assume that no heat is lost to or gained from the surroundings for either group. (a) If the final...

Heat Capacity Learning Goal: To understand the concepts of heat capacity, specific heat, and molar heat capacity. Heat capacity, C, is the amount of energy required to raise the temperature of a substance by exactly 1 degree Celsius. The energy needed to warm an object increases as the mass of that object increases. We see this in our everyday life. For example, we know that it takes much more energy to heat a large tank of water than a small...

For a three-dimensional (3D) solid, we have found the low-temperature heat capacity to be proportional to T3. How does it depend on the temperature for the two-dimensional (2D) graphene? Hint: In order to give a correct answer to this question, you have to know a curious fact about the phonon dispersion in graphene. We have seen that the acoustic phonon branches in both one dimension and 3D have a dispersion with ?(k) ∝ k. For graphene, this is not so:...

A homogeneous three-dimensional solid has a heat capacity at constant volume CV that depends on temperature T. Neglecting differences in the transverse and longitudinal waves in the solid, there are 3N vibrational modes, where N is the number of atoms in the solid. Here, the solid has N = 3.01 x 1023 atoms which occupy a total volume V = 18.0 cm3 . There are two transverse shear waves and one longitudinal wave; all waves have the same speed of...

Entropy & heat capacity: The definitions for the entropy and heat capacity are pretty similar. So, what is actually the difference between dS=dq/T and cp = dq/dT? Apply a simple and plausible example to illustrate the different nature of S and cp.
