Explanation:

The conduction is the process in which the heat transfers within the material like heating up metal rod.

The radiation can be defined transfer of energy from body in the form of particles or wave like radiation from nuclear bomb.

The convection is the process of heat transfer by the movement of warm gas or liquid in which warm air rise and cool air sink.

Here when tea when we swallow tea the motion of molecules in the tea rise and there is transfer of heat.

concave lenses are used here. they spread the light out before it reaches the convex lens in the eye, therefore letting the image focus directly on the retina. hyperopia is known to you probably as farsightedness.
