A: A means of heat transfer by movement of the heated substance itself, such as by currents in a fluid. 100
A: A material that is a poor conductor of heat and that delays the transfer of heat. 200
A: A means of heat transfer within certain materials and from one material to another when the two are in direct contact.
A: This is the longest wave that can be seen, and it is around 500 degrees Celsius.
A: At 1200 degrees Celsius, radiation gives off yellowish light, better known as this.
A: Radio waves, ultraviolet radiation, X rays, and gamma rays are examples of these.
A: Good absorbers are good emitters; poor absorbers are poor emitters, as stated in this.
A: Convection is an application of this principle, for all buoyed upward by denser surrounding fluid.
A: As air over the shore rises, cooler air from above the water takes its place (creating this.)
Q: If you blow on your hand, with your mouth open, your breath is warm. But if you pucker your lips, your breath is cooler. Why?
Q: Putting your fingers beside a flame is much safer than over top of it. Why?
A: Heat travels upward by air convection. Little air travels sideways.
A: Simply put: collisions between atoms or molecules and the actions of loosely bound electrons.
A: Wood, wool, straw, paper, and cork are poor conductors, but are top ______.
Q: A blanket does not truly give off heat. It slows the transfer of ______ ________ to your surroundings.
A: Little heat escapes from the house, keeping heat unable to escape and melt snow.
A: Radiation energy emitted from the earth after being absorbed from the sun.
A: The warming effect whose cause is that short-wavelength radiant energy from the sun can enter the atmosphere and be absorbed by the earth more easily than long-wavelength energy from the earth can leave.
Q: Our present environmental concern is that excess carbon dioxide and other atmospheric gases will trap too much energy, causing this.
Q: The radiant energy from the sun is composed of short waves and lets off three waves. What three waves?
