### What is the diagram for freezing and freezing point?

Absolute zero is the theoretical lowest possible temperature.
More formally, it is the theoretical temperature at which entropy
reaches its minimum value. The laws of thermodynamics state that
absolute zero cannot be reached using only thermodynamic means. A
system at absolute zero still possesses quantum mechanical
zero-point energy, the energy of its ground state. The kinetic
energy of the ground state cannot be removed. However, in the
classical interpretation, it is zero and the thermal energy of
matter vanishes.

###### Asked in Physics, Chemistry

### What state of matter has the least kinetic energy?

The state of matter than has the least internal kinetic
energy
(the kinetic energy of all the internal particles
relative to the center of mass of the system),
or the least internal + macrosopic kinetic energy,
is the same state as
"Which state of matter has the least thermal energy?".
(hint: it's not the gaseous state).
However, if you are asking what state of matter has the least
macroscopic kinetic energy:
Every state of matter can have systems with zero macroscopic
kinetic energy.
So none of them (or perhaps all of them) have the "least"
kinetic energy.

###### Asked in Kinematics

### Can it have kinetic energy but no momentum?

Momentum = mass x velocity
Kinetic Energy = 0.5 x mass x velocity2
If momentum equals zero, the only logical thing to assume is
that the velocity equals zero. If the velocity equals zero for
momentum, the velocity for your kinetic energy formula is also
equal to zero. Anything multiplied by zero is zero, so kinetic
energy would be zero if momentum is zero. So the answer is no.

### When does the value of mass is 0?

Mass can only be zero when energy is also zero. Einstein's
mass-equivalence equation e = mc2 supplies the relationship between
mass and energy. Since c2 is constant, i.e. about 9 x 1018 (m/s)2,
in order for mass to be zero, energy must also be zero.
In the Standard Model, only the photon and the gluons are
massless, that is, in their rest state.

###### Asked in Science, Physics, Energy, Quantum Mechanics

### What is zero point energy?

Answer
Zero-point energy (not to be confused with Vacuum Energy) is the
lowest possible energy that a quantum mechanical physical system
may have and is the energy of the ground state. This energy comes
from the fact that after you remove all thermal and kinetic energy
from an atom there is still quantum mechanical harmonic vibration
that arises due to the Heisenberg Uncertainty Principle. This
energy, so far, can not be taken away from a system.

###### Asked in Science, Physics

### Can a system of two or more objects have a total kinetic energy that is zero but a total momentum that is not zero?

No.
If the total kinetic energy is zero, this undeniably means that
the bodies are not moving. If they are not moving, the total
momentum should be zero. According to me, if the total kinetic
energy of a system of bodies is zero, the total momentum should
also be zero.
The reverse is true though: A system can have zero momentum
(bodies of equal mass move in opposite directions) but a kinetic
energy that is not zero.

### What is a net zero energy building?

Net Zero Energy means that a building balances its energy needs
with energy produced from renewable, zero-emission sources. While
Net Zero Energy buildings may seem cutting edge, they will become
status quo faster than you think. GSA's Sustainable Facilities Tool
goes into depth on legislation, programs, and case studies
pertaining to Net Zero Energy.
