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.
I know my math and your answer is going to be A.
Changing the subject of the formula
A whole turn is 360° so to turn 40° clockwise is equivalent to turn 320° counterclockwise.
