Question

a certain type of stainless steel cookware has a layer of copper applied to the bottom to help it heat evenly. the copper transfers heat to the pan by select question 8 6.25 pts in a swimming pool, the water near the surface is slightly warmer. the warm water rises because of select question 9 6.25 pts one end of a copper rod is placed in a flame of a bunsen burner. small pieces of wax placed along the rod melt at progressively larger distance from the flame. heat is transferred through the rod by select

Explanation:

1. For the stainless - steel cookware with copper layer: Heat transfer in a solid (copper layer) is mainly by conduction. Conduction is the transfer of heat through a material without the bulk movement of the material itself.
2. For the swimming pool water: The warm water rises due to convection. Convection is the transfer of heat by the bulk movement of a fluid (water in this case). Warm water is less dense than cold water, so it rises.
3. For the copper rod with wax pieces: Heat transfer through the copper rod is by conduction. The heat from the flame is transferred from one end of the rod to the other through the vibration and collision of atoms in the copper.

Answer:

Question 7: Conduction
Question 8: Convection
Question 9: Conduction
