Take 1.5-2 litre water in a stainless steel pot or other container and warm it till boiling. Now, remove the pot from the flam. Take water with normal temperature in a glass or test tube and measure its temperature. Now, put the test temperature. what is the difference in both temperatures?You will find that the temperature cold water rise an temperature of hot water decreases a little. Thus"Heat flows from the object with high tempoerature towards object with low temperature.""The temperature of the object which releases heat becomes low whereas the temperature of the object which receives heat becomes more."Find out the temperature of both water containers after one hour. You will find that temperature in both the water containers is the same." The hot or cold object exchange heat till the temperature of both becomes the same."1. What is the difference in temperature of both water ?2. What conclusion do you draw from above experiment?3. What change you noticed in the temperature of hot and cold water? ‘4. Why does the temperature of both the containers become equal at the end of experiment? |

Answer» 1. The temperature of normal water has increased while the temperature of boiled water has decreased. 2. From the above experiment we conclude that heat flows from a body of higher temperature to a body of lower temperature. 3. The temperature of hot water has decreased and that of cold water has increased. 4. The exchange of heat between hot and cold water containers till the tempertaure of both become equal. Therefore, at the end of experiment temperature of both the containers becomes equal. |
