Answer:
225,563,910 m/s
Explanation:
speed of light in water = speed of light in the air/refractive index
speed of light in water = 3.00 x 10^8 m/s/1.33
speed of light in water = 225,563,910 m/s
Answer:
A
Explanation:
the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
Elements in the same group have the same number of outer-shell electrons or "valence" electrons, so they tend to react similarly, as they can form similar bonds.
Answer
A. Its volume is decreased
Explanation
If we compress a gas (decrease) without changing its temperature, the average kinetic energy of the gas particles remains the same.
At a constant temperature, the kinetic energy of particles remains the same. If the volume is reduced at a constant temperature, then the number of particles in unit volume or area increases. If there is an increased number of particles in the unit area then it increases the frequency of collisions per unit area.
At constant temperature, the smaller the volume of the container, the larger the pressure.
I would say that the answer has to be C
Since there is no change in mols on both sides of the equation the mass is constant
