Make sure that water is not so hot that you burn your hand



Fig. 4.1 Feeling water in three mugs


some cold and hot water in mug C. Now dip your left hand in mug A and the right hand in mug B. After keeping the hands in the two mugs for 2–3 minutes, put both the hands simultaneously in mug C (Fig. 4.1). Do both the hands get the same feeling?

Boojho says,“My left handtells me that the water in mugC is hot and the right handtells me that the same wateris cold.  What should Iconclude?"

Boojho’s confusion shows that we cannot always rely on our sense of touch to decide whether an object is hot or cold. Sometimes it may deceive us.

Then, how do we find out how hot an object really is? A reliable measure of the hotness of an object is its temperature. Temperature is measured by a device called thermometer.​
