Question

Let us say that you have prepared a cup of tea for yourself. The tea is very hot say at 80°C and so you leave it in a room with a temperature of 25 ° C for some time to cool down. Now, after some time you come back to find that the tea in the cup has cooled down to say 50°C and you have a sip of the same. It is not possible to have a scenario where the heat flows from the room at 25° c to the cup of tea at 80° C and heat it even further. Heat always flows from
a. colder object to hotter object
b. colder to hotter and again hotter to colder object
c. hotter object to colder object
d. none of these​

Answer 1

Answer:

option C guys or frnds

Explanation:

heat flows from hotter objects to the colder obejcts

Answer 2

Heat energy can be transferred from one body to the other or from one location in a body to the other. Study of the techniques and methods adopted to transfer heat energy is known as ‘Heat Transfer’. To facilitate heat transfer between 2 bodies there needs to be a temperature difference between them.This means that these bodies must be a 2 different temperatures one higher than the other to allow heat to flow from one body to the other.

This means that no heat transfer occurs between 2 bodies which are at the same temperature. At the same time, it is very important to note that heat only flows from a body at higher temperature to a body at a lower temperature. Although this may look obvious, this law is very important from the point of view of thermodynamics.
