Atmospheric pressure is simply the weight of air molecules present above the measuring point. Air molecules have mass. Bar is one of the units of pressure. Pressure is actually the force acting per unit area. Here is the conversion.
1 N/m2 = 1 Pascal
100,000 Pascal = 1 bar
You know that the atmospheric pressure is high near Earth’s surface and low at higher altitudes. (Read Atmospheric air pressure) This means the air is more compressed near earth’s surface than at higher altitudes.
Since the air is compressed at earth’s surface (low altitude) than at higher altitudes say a mountain, the temperature is high at low altitude.
Light year by definition: It is the distance that light covers in one year when it travels.
