0:00 Hello everyone.

00:01 So in this particular question we are asked that animals they can lose but they cannot gain heat and we are given with the following options.

00:11 So we need to tell that which of the following option is correct with respect to the question that is asked to us.

00:17 So let's discuss each and every option one by one.

00:23 So whenever we are talking about evaporation we all know that evaporation is used.

00:30 Used to lose heat that is animals use this process to cool down their body right so they cool down their body by sweating and the sweat that the body has made gets evaporated thus cooling down the surface right but this cannot be used to gain heat that means we are evaporating the fluids from our body surface and then gaining heat out of that process so our first answer is the correct answer but let's discuss the other options as well so now the second option that we are given here that is radiation so radiation is a process of transfer of heat right and this heat is transferred with the help of beam of radiant energy and this radiant energy is which is emitted by object so by radiation we can gain a person will gain heat in the body.

01:32 So now the next part of the question which is given to us that is convection.

01:37 So what happened that with the help of direct contact, right? in convection we can see that with the direct contact it will suppose the animal, it is lying on a hot surface, right? if that animal is lying on a hot surface, it will gain heat.

01:56 And this is known as gaining heat with the help of convection...
