Introduction

All us are quite familiar with the term "temperature". When we touch a hot object, we say "the object's temperature is high". On the other hand, we consider the temperature of ice as low, as for us "the ice is cold." In a certain sense, we define temperature as "the degree of hotness in an object". But this definition is intuitive, and it makes reference to our senses. We cannot use this approach to determine correctly the degree of hotness, i.e. the assign an exact numerical value to temperature. A cup of tea can be "warm" for one person who is inside the room and "very hot" for another person who is just entering house during a winter day. Thus, we must find a universally applicable way to measure the numerical value of temperature, i.e. of the degree of hotness in an object.

In this tutorial, we will explain in detail the meaning of temperature along with its units and measuring devices. Therefore, by the end of this tutorial, every doubt on this issue will be clarified.
