To answer the question, "We do not feel uneasy even under enormous pressure of the atmosphere above as well as around us. Give a reason," we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Atmospheric Pressure**: - The atmosphere exerts pressure on all objects, including our bodies. This pressure is known as atmospheric pressure, which at sea level is approximately 101.3 kPa (kilopascals). 2. **Internal Body Pressure**: ...

Cloud formation condition Consider a simplified model of cloub formation. Hot air in contact with the earth's surface contains water vapor. This air rises convectively till the water vapor content reaches its situation pressure. When this happens, the water vpor starts condensing and droplets are formed. We shall estimate the estimate the height a which this happens.We assume that the atmosphere consists of the diatomic gases oxygen and nitrogen in the mass proportion 21:79 respectively. We further assume that the atmosphere is an ideal gas, g the acceleration due to gravity is constant and air processes are adiabatic. Under these assumptions one can show that the pressure is given by p = p_(0) ((T_(0)-T_(z))/(T_(0)))^(alpha) Here p_(0) and T_(0) is the pressure and temperature respectively at seal level (z = 0),T is the lapse rate (magnitude of the change in temperature T with height z abive the earth's surface, i.e. T gt 0) .
