The diagram shows four thermometers, labeled W, X, Y, and Z. The freezing and boiling points of water are indicated. Rank the thermometers according to the size of a degree on their scales, smallest to largest.

Question

Quizplus · Accepted Answer

The size of a degree on a thermometer's scale is determined by the distance between the freezing and boiling points of water, divided into equal increments. In this case, we can see that Z has the smallest range between the freezing and boiling points, which means each degree on its scale will cover a smaller range of temperatures than the other thermometers. X has the next smallest range of the four, followed by W and Y, which have the largest range. Therefore, the correct ranking from smallest to largest degree size is Z, X, W, Y.
