How does pressure affect temperature. As I understand as you increase pressure temp increases and vice versa. However how fast do objects return to room temp in a vacuum? Conversly if that same object is put under pressure how does that affect it going to room temp after it's heated???

does the electrons revolve around the nucleus when it gets more energy as it is heated to a very high temperature.if it revolve so does the characters of the atom changes to that of an electromagnetic wave.

It is well known that bullets and other missiles fired at Superman simply bounce off his chest. Suppose that a gangster sprays Superman's chest with 3 g bullets at the rate of 100 bullets/min, and the speed of each bullet is 500 m's.
Suppose too that the bullets rebound straight back with no change in speed. What is the magnitude of the average force on Superman's chest from the stream of bullets? Why and how did you get your answer?

Would the magnetic field "going in" at the poles make a difference to the weight of a fixed mass of iron? What about a 1g magnet?

Mass is energy and energy is mass.
The photon is regarded as an energy packet.
Bearing that in mind. To accelerate an object towards the speed of light you need put energy into it. So adding energy increases its mass. As it becomes more massive more energy is required to accelerate it and so on exponentialy. Therefore the action of accelerating an object to the speed of light would make it infinitly massive and would take an inifintite amount of energy.
The photon travels at the speed of light therefore it should be infinitly massive and have used up all the energy in the universe to get there and so shouldn't exist.
Can anyone resolve this apparent contradiction, or is there something wrong with my argument. Hmmm

About the emotional consciousness of astrophysics, astronomers and nuclear physics about the Nobel Prize, which comes from the disturbance of morally transform their state of being, awake by the feeling of ignorance, which based the interpretation of the powers of the “Grand Atom” Universe mechanism, only founded in the Sun’s reaction, such as: light, mid atomic waves caused by the electrons’ ups and downs inside the atom, not considering the complete mechanism of the Universe: Sun (nucleus) interacting with the Interstellar System (finite surroundings) by the power of Planet Earth (center of balance), according to the book to be published by the projector and scientist self-taught person Tarcísio Brito.
