Why heat is only absorbed by an object when it is covered by an aluminium foil which remains cool?

The aluminum foil makes a good reflector for the infrared radiation. Although metals tend to be good conductors and aluminum is no exception, the fact that it is beaten extremely thin makes it difficult for to disperse throughout. As a result the aluminum stays relatively cool and the object in question continuously recycles the wasted heat energy that is emitted.

When you rotate a jar filled with water and a floating object on it object doesn't moves?
That's because - the rotational motion of the jar is 'absorbed' by the water. Therefore the movement of the jar never reaches the floating object and, since there's no forces acting on it, it remains stationary.
What does an object become when light is absorbed?
The object becomes darker in color. If all the light is absorbed, it becomes black.
When heat is absorbed by an object the speed of the particles in an object is?
increased.
When heat is absorbed by an object the speed of the particles in the object is?
increased.
Where does energy go when a light is absorbed by an object?
The energy will of course also be absorbed by the object. For example, when an object is in sunlight and absorbs part of the light, its temperature will increase.
What happens to light when it hits a coloured object?
It can be either reflected or absorbed. E.g. if the object is green, all the colours of light are absorbed except green. Green is reflected and not absorbed.
What happens when light hits an object it cannot pass through?
If the light can not pass through a object it is opaque . The light will reflect or be absorbed by the object.
When all colors are absorbed by an object the object appears to be what color?
Black
What does wet mean?

What happens when all colors are absorbed?
When all colours are absorbed in an object you will get the colour black
