A sample is termed REPRESENTATIVE SAMPLE if it has similar characteristics to the population being studied.
The representativeness of a sample is the extent to which its characteristics accurately reflects the characteristics of the population being studied.
Simple. Air has mass. And if air has mass it also has weight. You can feel air when the wind blows. Or do an experiment. Weigh an empty container. Then pump it to a vacuum. Weigh it again. The difference is the weight of the air inside.

I think false because no one knows what will happen in the future and anything is possible, although the population does increase it can still decrease by high amounts aswell, anything bad could happen any time. People may not even have money to survive but it really depends on what happens and what could happen in the future, no one really knows what will happen so this statement would be false.
Anyway have a nice day :)
