Question

open - ended questions: answer the following questions in complete sentences. 1. compare conduction, convection, and radiation in terms of how they transfer thermal energy. 2. why do you think an aluminum can was a good choice for our container?

Explanation:

1. Conduction transfers thermal energy through direct contact of particles in a solid or stationary fluid. Convection involves the movement of fluids (liquids or gases) to transfer heat, with warmer parts rising and cooler parts sinking. Radiation transfers thermal energy in the form of electromagnetic waves and can occur in a vacuum.
2. Aluminum is a good choice for a container because it is a good conductor of heat, allowing for efficient heat - transfer in some applications. It is lightweight, durable, and has good corrosion - resistance, which helps protect the contents and the container itself.

Answer:

1. Conduction is heat transfer by direct particle - to - particle contact in solids or stationary fluids. Convection is heat transfer by fluid motion with warmer fluid rising and cooler fluid sinking. Radiation is heat transfer via electromagnetic waves and can occur in a vacuum.
2. Aluminum is a good container material as it is a good heat conductor, lightweight, durable, and corrosion - resistant.
