Air is all around us.Air is Colourless and odourless .Air is invisible .
To feel the presence of air do the following things:
1. Blow air inside a balloon . Then leave it . You an feel it by presence of touch when air is coming out of balloon. 2. Blow air by your note book. You can feel its presence. 3.BY making paper kite and trying to fly it. 4. Riding the bicycle on windy day.
Air is colourless with static pressure. Air cannot be seen but can be felt.
1. We sense the difference between the air pressure and internal pressure in our body. The latter is changing according to external pressure changes, therefore you don't feel slow air pressure changes, but only abrupt ones.
2. The temperature of the air can be felt via sensors in the skin. More precisely, we feel the temperature of the skin, which is a function of air temperature, air humidity and to some extent relative velocity. But even at zero relative velocity, you feel the air temperature.
3. There is a feeling of air motion, sensed by the movement of the fine hair on your body, and, at larger velocities, also by differences in pressure and temperature between different parts of the body.
