Heat Transfer Word Search
This puzzle holds the three ways heat moves, conduction, convection and radiation, the insulator and the conductor, thermal energy and temperature, and the everyday examples a science class uses, from the metal spoon and the oven mitt to the sea breeze.
Heat always flows from warmer to cooler until both reach the same temperature, a state called thermal equilibrium. A spoon in hot soup warms by conduction, as fast particles bump into slower ones. Air and water carry heat by convection: warm fluid rises and cool fluid sinks, which is why land, warming faster than the sea on a sunny day, draws in a cool breeze off the water. Radiation needs no matter at all, and sunlight crosses 93 million miles of empty space.
People once thought heat was an invisible fluid called caloric. In 1798 Count Rumford noticed that boring out cannon barrels made heat without end, and argued it must come from motion. The Scottish scientist James Dewar built the first vacuum flask in 1892, and a German company began selling it as the Thermos in 1904. An igloo stays warm inside because packed snow is mostly trapped air, a good insulator.
