Why and how does heat transfer? When does it stop transferring?

The transfer of heat will continue as long as there is a difference in temperature between the two locations. Once the two locations have reached the same temperature, thermal equilibrium is established and the heat transfer stops.

Heat is transferred from a warm body to a cooler body. The temperature of the warm body drops while the temperature of the cooler body rises. When the two temperatures are equal, thermal equilibrium is attained, and the heat transfer stops.

Explanation:

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements
