Two containers X & Y are filled with equal amount of hot water & the temperature of thewater in the containers is measured with a thermometer some time later.it is observed that container X has a much lower temperature than container Y.Which of the following are the possible reasons? 1) Container X is black & container Y is silver. B) container X has a lid & container Y isnot covered. C) Container X is made of steel & container Y is made of clay. A) 1&2. B) 1 & 3. C) 2&3. D)1,2&3

Answer:
B) 1 & 2 will be the answer
The possible reason are 1 and 3.
Option (B) is correct.
Explanation:
1) Container X is black & container Y is silver.
2) container X has a lid & container Y is not covered.
3) Container X is made of steel & container Y is made of clay.
The possible reason are 1 and 3.
The reason is that black absorbs more heat than silver. Black absorbs all the heat and it will transfer the heat into the surrounding more rapidly as compared to silver in which the process of heat transfer into the surrounding is low and temperature of container x will be low than Y.
The second reason is that steed is a good conductor of heat than clay. Steel absorbs heat and transfers it into the surrounding more rapidly than clay which is a bad conductor and therefore the temperature of Y container will be high than X container.
