Suppose the scientist performs an experiment in which she cools the three gases. Will the changes in temperature be positive or

In the case that a scientist cools three gases in an experiment, the change in temperature will be negative for the experiment. This is because cooling results in a temperature lower than the original temperature. For example, a gas originally at 25°C when cooled to 20°C has a temperature change of -5°C.
