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.
Answer:
Compounds with Carbonate ions are less soluble than the compounds with Chlorate ions.
Explanation:
The reason is that the compounds with carbonate ions have less attraction between positive and negative charges. (Solvation)
Answer:
Changing the volume increases the area that the molecules collide with so the force is spread over a larger area.
Explanation:
The volume of a container is the space within the container. This is the amount of void the gas can occupy.
When the volume of a container is changed, the space either increases or decreases.
- An increase in volume creates more space within the container.
- This spreads out the force over a larger area.
When the volume of the container is reduced,
- the force is confined to much smaller space.
The frequency of collision is higher for tiny spaces.
But lower for a large volume.
