Mathematical Example: Temperature
Question: The temperature of body of a healthy man is 98.4°F. What would be the reading in Celsius scale? Given, Temperature in Fahrenheit scale, F…
Establishing a Relation Among different Scales of Temperature
Generally, there are three common types of temperature units: Kelvin (K), Celsius (C) and Fahrenheit (F). Let A and B be the lower fixed point…
Explain Relation among Celsius, Fahrenheit and Kelvin scale
A scale of temperature is essential to indicate the temperature of a body accurately. Two definite temperatures are taken as constant to prepare a temperature…
What is Heat, in terms of Energy?
Heat is a kind of energy which creates the sensation of hotness and coldness. Heat flows from hotter to colder bodies. Therefore the energy that…
Explain Molecular Kinetic Theory of Matter
The basic conception of the molecular kinetic theory of matter is to consider that the molecules of a matter are in motion. The kinetic theory…
