One way to store a lot of energy is to compress air in a large cave. The air starts at the corner marked by the black dot, where P = 1 atmosphere, V = 1 cave volume (let's choose 1,000,000 cubic meters), and T = 300 K. It is then adiabatically compressed to half the volume by a pump. As the air comes out of the pump it is hotter (how hot? what is the pressure?), but it cools to 300 K again at constant volume (what is the temperature now?). Later, the air expands adiabatically running a generator, ending at the initial volume. It is now colder than 300 K (how cold?) but it warms up to end at the original temperature, pressure, and volume.How much work did the pump do? How much energy was given to the generator

Energy store. Fats and oils are good sources of energy, whether
they are burned in air or metabolized in the body. Regardless of
the process, there are certain things in common
a) Besides the oil, what other
ingredient is needed to produce energy?
b) What are the end products of
the burning or metabolism of oil?
c) Where does the energy produced
come from?
d) What would you make of an ad

A spring is mounted over an air track in such a way that the one
end of the spring is fixed and the other is connected to a spring
scale. When the spring is stretched to 0.01 m a force of 1 N is
registered on the spring scale. The spring is relaxed and a glider
of 0.43 kg (resting on the air track) is connected to it. The
glider-spring system is then pulled to the right through a distance...

It is desired to air-condition a small one-room store located on
the first floor of a building several stories in height. The store
is 20' wide and 40' deep, and the ceiling height is 12'.The front
wall, which faces north, may be condidered as 100% glass. The
partitions between this store and the stores on either side are 4"
cinder tile, platered on both sides; and the rear wall, which
contains 40 sq ft of glass, is of 4" brickbacked...

Ocean waves carry a lot of energy – according to the Bureau of
Ocean Energy Management, about 2,640 TWh/yr (terawatt-hours per
year) off the immediate coast of the US. 1 TWh/yr is enough to
power 93,850 average U.S. homes. If some of this energy could be
harnessed, it could be a great source of clean, renewable energy.
Assume that an ocean wave is described by a sinusoidal transverse
wave along the surface of the ocean and that has an amplitude...
