Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.

Today you use a process of heating liquids to prvent spoiling by bacteria and othe microorganisms What is that process called and for what food is it used?
pasteurization, this is mainly used for milk or milk products.
Can someone get ill if you put hot food directly into the fridge?
Heating food will destroy any pathogens in it. Cooling it back down doesn't cause these pathogens to grow again, but they can if there is a source in the fridge from which they can spread to this new food. Refrigeration is only used to keep food from spoiling for a longer period of time rather than simply leaving it out. It can only encourage bacteria growth if the interior (and food) is cool AND humid.
Why are preservatives used in foods?

How was most food preserved in the past and what invention changed that?
In the past people used to pickle or cure their foods to keep the food from spoiling. And over the many years the refrigerator and freezer have made these methods less of a necessity than they once were.
