According to Chinese expert Li Xu from QuantumCTek, “absolute zero,” at approximately minus 273.15 degrees Celsius (0 Kelvin), is commonly known as the “lowest temperature in the universe.” ...

measures temperature using the Celsius scale and thermodynamic temperature using the kelvin scale, which is just the Celsius scale shifted downwards so that 0 K= −273.15°C, or absolute zero.

This is called a "temperature," because the hotter fire gets, the more it changes from a warm yellow glow to white. The lower the Kelvin rating, such as the common incandescent/tungsten bulb ...

Imagine a gas is trapped inside a container which has a fixed size (its volume cannot change). Gas pressure is caused by the collisions of the gas particles with the inside of the container as ...
