Space invaders land on earth. On the invaders’ temperature scale, the ice point is at 25°I (I = invader), and the steam point is at 153°I. The invaders’ thermometer shows the temperature on earth to be 55°I. Using logic similar to that in Example 1 in the text, what would this temperature be on the […]
