Safety and Accident Prevention

Dalton's Law of Partial Pressures
Dalton's law of Partial Pressures states that the pressure of a mixture of gases is the sum of partial pressures of individual components of the gas mixture. Each gas in the mixture is assumed to be an ideal gas.

Water Vapor Conformance to Dalton's Law
Water vapor though is a gas does not conform to Dalton's law. Water vapor is dependent on its temperature and not on its fractional concentration in the mixture.

Sources of Pressure Hazards
The most common use of Dalton's Law is seen with water vapor. A common way of collecting gas during the experiment is by trapping it over water. However with this setup there is an unavoidable problem. The gas gets saturated with water vapor due to which total pressure inside the bottle is the sum of two pressure- gas pressure and pressure of water vapor. It creates pressure hazard which could be very dangerous. To eliminate this problem we have to get rid of water vapor.

In industrial setup pressure is frequently used to move ...
