The pleura is the membrane that covers the lungs, according to InnerBody. The pleura consists of two layers, with the parietal pleura forming the membrane's outer layer and the visceral pleura forming the membrane's inner layer.

Kinetic Energy K.E = 12mV2  or 

K.E ∝V2, Where 'm' is the mass and 'v' is the velocity of molecules.

Velocity is proportional to temperature. Hence, KE is proportional to temperature and would increase with temperature.

Parabola, because when the coin is dropped at a particular point, it has the same velocity as the running train. So by Newton's first law, it continues its motion horizontally with that velocity. But then, it is also pulled down by earth's gravity continuously. In this situation its horizontal motion gives way to the parabolic motion until it reaches the ground.

Cohesion refers to attraction between molecules of the same kind while adhesion refers to attraction between different kinds of molecules
