No, its normal maximum speed, which occurs as a plane-wave in free space, the speed is a constant called c, defined as 2.99792458E8 m/s.
In denser media, which are by definition all media, the speed is reduced. There are devices such as waveguides in which the phase-velocity exceeds c, but then the group-velocity, which is its reciprocal 1/c, is less than c.

When faster moving and slower moving particles collide which particles gain energy?
It depends upon the mass of the particles also. Assuming equal mass, then the slower moving particle gains some energy, and the faster moving particle loses energy. However, if the slower moving particle had greater mass, it could transfer energy to the faster moving particle.
What does heat energy do to a material?
all particle made up of particles,.whena material give more heat energy the particles move faster faster moving particles give them a high temperature..when heat energy is taken away from particles they slow down and so amterial has low temperature.in any material there must be some particles which are slower moving and having less energy and some are fast moving having high energy .
Does sound travel faster or slower through a solid than through air?
sound travels faster through a solid than through air
Does light travel faster in diamond or water?
Light travels slower through denser media, so it travels faster through water than through a diamond.
Is pressure higher or slower when molecules move faster or slower?
Molecules move more rapidly when heated as their kinetic energy is increased so their speed increases.
Do faster atoms have more potential energy than slower atoms?
faster atoms have more kinetic energy than slower atoms do.
Does sound travels faster or slower through a solid than through air?
Faster.
Does increased energy increased that particles are moving faster r slower?
Increased energy makes particles move faster.
Explain the transformation from ductile to brittle structure?
This transformation has everything to do with the cooling rate of the material. A slower cooling rate will yield a tougher more ductile material structure, and a more rapid cooling rate will yield a hard and brittle material. A slower release of energy will give more space between the atoms in the material, faster energy losses gives a more dense atomic structure.

A molecule moves faster or slower depending on the amount of what energy?
Kinetic
Do High glycemic foods provide energy at a slower rate?
no, faster.
Is the speed of sound in cork greater than speed of sound in water?
No. The denser the material, the faster sound moves through it.
Does sound travel faster or slower through a solid than through air?
sound travels faster through a solid than through air
When you add energy to the particles move?
faster. and matter then would move slower
What is the factor that causes the larticlew to move faster or to move slower (matter?
Energy
