Answer:
Sum of their partial pressures
Explanation:
If two gases are present in a container, the total pressure in the container is equal to the sum of their partial pressures.
This solution is based on the Dalton's Law of Partial Pressures.
Dalton's Law of Partial Pressure states that "the total pressure of a mixture of gases is equal to the sum of the partial pressures of the constituent gases".
A partial pressure is the pressure a gas would exert if it alone occupied the volume of the gas mixture.
Answer:
Two methods which help us to conserve water are:
Sprinkler irrigation system: this irrigation has an arrangement of vertical pipes with rotating nozzles on the top. It is more useful in the uneven and sandy land where sufficient water is not available.
Drip irrigation system: this irrigation system has an arrangement of pipes or tubes with very small holes in them to water plants drop by drop just at the base of the root. It is very efficient as water is not wasted at all.
