selma made a diagram to compare convection and radiation. which label belongs in the area marked x? must involve temperature differences between substances or objects only occurs when molecules are in direct contact involves the movement of fluids based on density differences can occur where there is little or no matter

Answer

Brief Explanations:

Convection and radiation are heat - transfer methods. Both require temperature differences between substances or objects for heat transfer to occur. Convection involves fluid movement due to density differences and requires matter. Radiation can occur in a vacuum (little or no matter) and doesn't need direct molecular contact.

Answer:

Must involve temperature differences between substances or objects
