Answer 1

Here are the answers to your questions based on the scenarios provided:

1. Your computer leaves the desk feeling very hot after you have been using it for a while.

   • Answer: conduction (The heat from the computer is transferred to the desk via direct contact.)

2. The ocean circulates around the Earth as cool water sinks and pushes less dense, warmer water out of the way.

   • Answer: convection (This describes the movement of fluids where cooler, denser water sinks and warmer, less dense water rises.)

3. A very dense metal rod and a wooden stick are both placed on a heated surface. The metal rod feels much hotter much faster than the wooden stick.

   • Answer: conduction (Heat is transferred through direct contact with the heated surface, and the metal conducts heat better than wood.)

4. Classify the following word/phrase: kelvin scale.

   • Answer: temperature (The Kelvin scale is a scale for measuring temperature.)

5. Classify the following word/phrase: electromagnetic rays.

   • Answer: heat transfer (Electromagnetic rays, such as infrared radiation, are a means of heat transfer.)
