What are the different temperature scales used? What are the relations among them?

What is the mass of a photon, people say that its massless, if it was massless, then won't it accelerate to infinite velocity if it is ejected from a light bulb, because the bulb gives it some energy, and if it had mass, most of the energy would be used to accelerate that mass, as kinetic energy is (mv^2)/2 but as there is no mass,therefore, the v should increase to infinity, in order for the equation to still hold valid, therefore, the photon is either stationary with the frame of reference, or is moving at infinite velocity, but still we can see that light travels at the speed of light, so it should have some mass which limits it to move at that speed, and does its mass change when it's moving? because if its mass didn't change then it should have accelerated more than the speed of light, but it doesn't no matter how much energy you provide a photon, I,e photons of radio waves and photons of gamma rays all travel at the same speed. please clarify my doubt, and please don't tell me that I don't know special relativity and Lorentz transformation, I have asked all my teachers at school they tell me that I don't know special relativity so I won't be able to understand it... please give me the answer to this question.

1. A BEAKER WEIGHS 120 g WHEN EMPTY AND 280 g WHEN FILLED WITH KEROSENE. FIND THE VOLUME OF THE BEAKER.     THE DENSITY O KEROSENE = 800 kg / m3.

 

2. A METAL BALL WEIGHS 1.8 kg. THE VOLUME OF THE BALL IS 250 cc. FIND THE DENSITYOF THE METAL.

 

3. WHAT DOES "CC" MEANS?

 

A BEAKER WEIGHS 120 g WHEN EMPTY AND 280 g WHEN FILLED WITH KEROSENE. FIND THE VOLUME OF THE BEAKER. THE DENSITY OF KEROSENE = 800 kg / m3. 

 

THE CAPACITY OF AN RD BOTTLE IS 50 cc ANDITS MASS IS 24.5 g WHEN EMPTY. FIND ITS MASS WHEN IT IS FILLED WITH A LIQUID OF DENSITY 800 kg / m 3.

 

THE MASS OF AN EMPTY RD BOTTLE IS 24.5 g. ITS MASS IS 74.4g WHEN FILLED WITH WATER AND 87 g WHEN FILLED WITH A LIQUID. FIND THE RELATIVE DENSITY OF THE LIQUID.
