Read each question carefully and answer to the best of your ability. Show all your work where applicable.
1. Which of the following best describes convection?
Heat transfer through direct contact.
Heat transfer through electromagnetic waves.
Heat transfer through the movement of fluids.
Heat transfer through a vacuum.
2. In a convection current, warm fluid rises because it is:
More dense than the surrounding fluid.
Less dense than the surrounding fluid.
At a lower temperature.
Under greater pressure.
1. Convection is a primary method of heat transfer in and .
2. The transfer of heat by the movement of heated particles is called .
3. A convection current is formed when a fluid is heated, becomes less , and .
1. Explain the process of heat transfer by convection using a real-world example.
2. How does the density of a fluid change when it is heated, and how does this change contribute to convection currents?
Observe the diagram below showing convection currents in a pot of water. Label the arrows indicating the direction of heat transfer and fluid movement.
1. Convection can occur in solids.
True
False
2. Hot air rises and cold air sinks due to convection.
True
False
