Concept explainers

The flow of energy from one region to another region is referred to as energy transfer. Since energy is quantitative; it must be transferred to a body or a material to work or to heat the system.

Molar Specific Heat

Heat capacity is the amount of heat energy absorbed or released by a chemical substance per the change in temperature of that substance. The change in heat is also called enthalpy. The SI unit of heat capacity is Joules per Kelvin, which is (J K-1)

Thermal Properties of Matter

Thermal energy is described as one of the form of heat energy which flows from one body of higher temperature to the other with the lower temperature when these two bodies are placed in contact to each other. Heat is described as the form of energy which…

Chapter 39, Problem 39.60P

An Ideal Blackbody. A large cavity that has a very small hole and is maintained at a temperature T is a good approximation to an ideal radiator or blackbody. Radiation can pass into or out of the cavity only through the hole. The cavity is a perfect absorber, since any radiation incident on the hole becomes trapped inside the cavity. Such a cavity at 400°C has a hole with area 4.00 mm². How long does it take for the cavity to radiate 100 J of energy through the hole?

While cruising down University Boulevard you are stopped by a cop who states that you ran a red traffic light. Because you don't want to pay the stiff fine, you are attempting a physics defense. You claim that due to the relativistic Doppler effect, the red color of the light λ=616 nm appeared green '=531 nm to you. The cop makes a quick calculation of his own and rejects your defense. How fast, in terms of your speed u divided by the speed of light in vacuum c, would you have to drive to justify your claim? Note that the speed u is taken to be a positive quantity. U 4.0 C
