This document contains a heat and temperature quiz with 14 multiple choice questions about energy transfer and heat flow. The questions cover topics like where a car gets its energy to warm up, how energy flows from the sun to earth and between objects at different temperatures, how polar bears retain heat and why their coats help insulate them, and different types of heat transfer like conduction, convection and radiation.
