Question

The hot water in the tumblers slowly cools down. Is it because the cold is transferred from the water in the tumblers ?

Please give a proper answer or I will report

​

Answer 1

Answer:

the tumbler and water makes a open system in which both matter and energy can transfer .

so when the water is kept in a tumbler it decipates the heat energy through the tumbler walls into the environment ,due to the temperature difference of water and atmosphere.

here the point to bhe noted is that ,

HEAT IS TRANSFERRED NOT THE COLD!!
