Question
1). It had long been known that there is a coldest possible temperature, called absolute zero, the temperature of an object if all heat could be removed from it. On the Fahrenheit temperature scale, absolute zero is about 460 degrees below zero. On the absolute or Kelvin temperature scale (named after the nineteenth-century scientist Lord Kelvin), absolute zero temperature is assigned the value 0. Has absolute zero ever been reached? As temperature approach absolute zero what happens to some metals?
2). Please define derivative and explain in your own words why it is one of the two most important concepts in all of calculus?
Explanation / Answer
1) Absolute zero temperature has never been reached. Though some temperatures close to it has been achieved using metals usch as cryocoolers etc.
2) Derivative of a function with respect to a variable can be thought as rate of change of the function with change in that variable.There are two major concepts in Calculus, namely, Derivatives and Integrals. Derivatives are basically, rate of change of one quantity with respect to the other quantity. Integrals are used to study the overall behaviour of a process based on the behaviour of an element of the process.
