Q: What is the primary mode of heat transfer in a vacuum?
Solution:
In a vacuum, there are no particles to conduct or convect heat, so radiation is the only mode of heat transfer.
Steps: 7
Show Steps
Step 1: Understand what a vacuum is. A vacuum is a space that has no matter or particles in it.
Step 2: Know the three main modes of heat transfer: conduction, convection, and radiation.
Step 3: Realize that conduction requires particles to transfer heat through direct contact.
Step 4: Understand that convection also needs particles to move heat through fluids (liquids or gases).
Step 5: Since a vacuum has no particles, conduction and convection cannot occur.
Step 6: Learn that radiation is the transfer of heat through electromagnetic waves, which can happen in a vacuum.
Step 7: Conclude that in a vacuum, radiation is the only way heat can be transferred.
