laboratory experi-ment rather than a field study if both investigations
allow you to collect similar information?
1. It is possible to change only one variable at a time.
2. Working conditions are always better indoors.
3. The measuring equipment will be more precise.
4. The data processing can be done right there.: 1. It is possible to
change only one variable at a time.

11. The kinetic theory of gases is based on the assumption
that the molecules that form the gas are in random motion and
bounce off the walls of their container and off each other as if
they were billiard balls. The forces between real molecules are
more complicated. This is an example of?
1. using a model
