Temperature
We will discuss here about the concept of temperature. We have already learned about various types of measurements like length, mass capacity and time. But if we have fever, non of these measurements can help us to find out how high a fever we have.
The temperature of an object is measured by an instrument is called
thermometer. Now we will learn about the measurement of temperature.
Take two cups, one containing normal water and another containing hot water. Put your fore finger of one hand in one cup and of another hand in the other cup. We find, one contains cold water and the other contains hot water. But the question is how much cold and how much hot. To find this out, we need some measure of hotness or coldness.
Temperature
is the degree of hotness or coldness of a body. The instrument which
measures the temperature of body is known as thermometer.
Each thermometer has a scale. Two different temperature scales are in common use today:
1. The Fahrenheit Scale
2. The Celsius Scale
Thermometer has scale in degree Fahrenheit (℉) and in degree Celsius (℃). The Fahrenheit scale has the melting point of ice at 32° F and the boiling point of water at 212° F. Thus, the Fahrenheit scale is marked from 32° to 212° where 32° F shows the freezing point of water and 212° F shows the boiling point of water. At present most of the countries use the degrees Celsius thermometers. The Celsius scale (is also called centigrade scale) thermometer has 0° C as freezing point of water and 100° C as the boiling point of water.
On comparing the Celsius and Fahrenheit scale we find:
For Example:
Write True or False.
1. The instrument used to measure body temperature in thermometer -----
True.
2. The normal body temperature is 98.6°F ----- True.
3. The liquid inside the thermometer is mercury ----- True.
4. The unit of measure of temperature is inches ----- False.
5. 0°C is cooler than 0°F----- False.
