What is thermal energy?
1. A form of radiant energy.
2. How fast molecules of a substance are 'jiggling'.
3. The same thing as the temperature of an object.
4. The energy that is transferred from a warmer object to a cooler one.
Homework Answers
Option 2, how fast the molecules of a substance are jiggling.
Thermal energy is defined in terms of the kinetic energy of the particles making a substance. In other words thermal energy refers to the kinetic energy of a substance at particle level. The particles of matter continuously juggle around in a chaotic manner or vibratory motion. The measurements of this jiggling is thermal energy. Greater the movement, higher the thermal energy.
Radiation is a form of energy when thermal Energy of a substance is enough to give off energy. Test transfer of funds thermal Energy is known as heat. So correct option is the second.

When two objects are in thermal contact heat energy is transferred from the hot to the cold object until the temperature of both becomes equal (i.e., the objects are in thermal equilibrium). Suppose you pour 20-gram milk at 200C into a cup of 80-gram tea at 920C. Assume the specific heat of tea is 4.2 J/gram.0K and that of milk is 3.9 J/gram.0K Assuming no heat is lost into the surrounding air what is the temperature of the tea and...

1. The Fermi temperature of a substance, TF, is the temperature at which the thermal energy of the substance equals the Fermi energy: k TF = EF, where k is Boltzmann's constant. This can be thought of as the temperature at which thermal effects of a system are comparable to quantum effects due to Fermi statistics (which follow from the Pauli exclusion principle for fermions). (a) Determine the Fermi temperature of copper. (b) For copper at room temperature, do you...

How much thermal energy is transferred to the system
A diatomic ideal gas expands from a volume of \(v_{A=100 m^{3}}\) to \(v_{B=300 m^{3}}\) along the path shown in the figure below. The initial pressure is \(_{P_{A}=200 x+10^{5} p_{2}}\) and there are \(73.4\) mol of gas.(a) Calculate the work done on the gas during this process.(b) Calculate the change in temperature of the gas.(c) Calculate the change in internal energy of the gas. (Take the molar specific heat of a diatomic gas for this process to be \(C_{p}=\frac{7}{2} R\)(d) How...
