How will you compare the temparature reading in cup a to that cup c
Answers
Answer:
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

Answer:
Heat
We had learnt that woollen clothes are made from animal fibres. You also know that cotton clothes are made from plant fibres. We wear woollen clothes during winters when it is cold outside. Woollen clothes keep us warm. We prefer to wear light coloured cotton clothes when it is hot. These give us a feeling of coolness. You might have wondered why particular types of clothes are suitable for a particular season.
In winter you feel cold inside the house. If you come out in the sun, you feel warm. In summer, you feel hot even inside the house. How do we know whether an object is hot or cold? How do we find out how hot or cold an object is? In this chapter we shall try to seek answers to some of these questions.
