Q. Describe about temperature scales?
The temperature of an entity explains how hot or cold the object is relative to other objects. Scientists utilize two temperature scales-the Celsius scale and the Kelvin scale-to measure temperature. You will be utilizing the Celsius scale in most of your experiments. On the Celsius scale the freezing point of the water is defined as 0 degrees and the boiling point of water is defined as 100 degrees.
