Does the big bang theory propose that all the matter and energy in the universe was once compressed into an extremely small volume?
Absolutely not.
This is a common misconception, not helped by popular presentations and by statements that "the Universe" was once the size of a proton.
The problem comes about partially due to the careless failure to distinguish between "the entire Universe" and "that part of the entire Universe that we can presently observe." Many people -- scientists included -- refer to both as simply "the Universe" without making clear that the latter is (at most) an infinitesmal subset of the former.
The present observable Universe is a sphere of radius about 46 billion light years. THAT small fraction of the total Universe was, indeed, the size of a grapefruit at one time. How much larger the ENTIRE Universe was at that time is, at present, impossible to determine -- and may always remain unknowable. The entire Universe may be a "mere" 100,000 times large than the observable Universe, or infinitely large. The only guesstimate ever made was that our entire Universe must be no less than 10^23 times larger than the observable universe.
Thus, what BB cosmology states is that our Universe was once un-imaginably denser than it is now.
Also, please be aware that BB cosmology does NOT state that matter was compressed into a smaller volume. Our Universe is not becoming less dense because matter is spreading out through empty space. It is becoming less dense because SPACE ITSELF is expanding (not exploding) -- matter is simply coming along for the ride.

Which term best describes conditions immediately following the big bang?
The term that best describes the conditions immediately following the big bang is "hot and dense." During this time, the universe was filled with extremely high temperatures and energy, with all matter and energy compressed into a very small, dense space.
What is energy content of compressed air?
The energy content of compressed air is typically measured in terms of energy density, which is lower compared to other energy storage technologies such as batteries or gasoline. The energy content of compressed air is dependent on the pressure at which it is stored and the volume of the storage vessel. Compressed air is often used as a form of energy storage in applications where high power output and short duration energy release are required.
What is the ultimate fate of a closed universe?
Scientifically, one present theory suggests that it will keep on expanding forever and eventually have maximum entropy. There are certain unexplained or not fully understood reasons why this will not happen. No absolutely certain answer can be given. Religions will give their own answer, none of which are in agreement.
What is the majority of the energy in our universe?
Something called "dark energy" which provides almost 70% of the total energy in the observable universe and is causing the expansion of the universe to accelerate (instead of decelerate as expected in the basic big bang model of the universe).
What would be the kinetic energy of particles of gas when it compressed in a cylinder?
When a gas is compressed, its temperature tends to increase. That means that the average kinetic energy per particle also increases.
What is compressed energy?
Compressed energy refers to energy that is stored in a compressed form, such as in compressed air tanks or compressed natural gas tanks. This energy can be released and harnessed for various purposes, such as powering vehicles or machinery.

How is the energy in food compressed?
The energy in food is compressed because of burning process
Compressed springs are what kind of energy?
The potential energy of a spring is defined by this equation: U=.5kx2 U= potential energy (in joules) k= the spring constant x= the displacement of the spring from equilibrium. (the amount that the spring is stretched or compressed) This equation tells us that as a spring is compressed by a distance x, the potential energy increases proportionately to x2
What color stars with q?
Quasars are not actually stars, but extremely energetic and distant objects in the universe, emitting massive amounts of energy.
What does energy have to do with the universe?
Energy is the fuel supply for the universe. No energy no motion.
The sum of all matter and energy that exists that has ever existed and that ever will exist?
The sum of all matter and energy in the universe is known as the observable universe, which includes everything that can be detected with current technology. It is constantly changing and expanding due to various natural processes. The total amount of matter and energy in the universe is believed to be finite but extremely vast.
What energy is in compressed spring?
Elastic potential energy
What kind of energy is stored in any compressed or stretched objects?
Elastic potential energy is stored in compressed or stretched objects. This type of energy is potential energy that is stored when an object is deformed (compressed or stretched) and has the potential to return to its original shape.
What kind of energy does compressed springs released?
Compressed springs release potential energy stored in the deformation of the spring when compressed. This potential energy is then converted into kinetic energy as the spring returns to its original shape and releases the stored energy in the form of mechanical work.
What is elastic energy?
Elastic energy is the energy stored in an object when it is compressed, stretched, or deformed. It is a form of potential energy that can be released when the object returns to its original shape. Examples include a stretched rubber band or a compressed spring.
Is the energy stored in a compressed spring called strain energy?
Yes, the energy stored in a compressed spring is commonly referred to as potential energy, specifically elastic potential energy. The spring store this energy by virtue of its deformation or change in shape due to compression.
