This theory<span> is based on the following </span>postulates<span>, or </span>assumptions<span>. Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion. These particles move in a straight line until they collide with another </span>particle<span> or the walls of the container.

Answer:
2)Both the salt dissolving and the evaporation of water are physical changes.
Explanation:
The two kinds of changes that has occurred are both physical changes.
Dissolution of a solute such as salt in water and evaporation of water from a solution are physical changes.
A physical change is one in which the physical property of matter is altered. Particularly the state and the form.
In many of these cases, the change is easily reversible.
Since this change is reversible in that we were able to collect the salt back, this is a physical change.

Modern Agriculture - The agricultural practices with modern technique like Fertilizers, Innovative hybrid seed, and utilization of machine call modern Agriculture.
Advantages -
Feeding to the population without scarcity of food grains.
Optimum Utilization of land (Crop intensity more then 300%)
Increased production of food grain.
Global Market - even our mangoes available at US and we are getting California apple too.
Due to factories and Machine use this industry is growing to and empowering good employment.
I hope this helps you :)
