Answer to Question 1

1. Conduction  heat transfer by direct contact form molecule to molecule. When a metal rod is heated on one end heat travels from that end to the cooler end through the rod.

2. Convection  heat transfer by circulating a fluid to distribute the heat. The air circulating inside older refrigerators is an example of natural convection.

3. Radiation- heat transfer by waves of electromagnetic radiation. Being heated by a fire is an example of radiant heat.

Answer to Question 2

The greater the temperature difference the faster the heat transfer.

This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
