🔍 Key Concepts

• Methods of heat transfer: conduction, convection, radiation • How heat moves through solids vs liquids and gases • The role of direct contact between molecules in heat transfer

💭 Think About

• Which method of heat transfer depends on direct contact between particles inside a material, rather than movement of the material itself? • In which heat transfer method does the substance stay in place while energy moves through it? • Which choices describe real scientific processes, and which one looks made‑up or incorrect?

✅ Before You Answer

• Identify which process is associated mainly with solids rather than fluids (liquids and gases). • Eliminate the option that is not a standard scientific term for heat transfer. • Recall that in this process, heat moves from hotter to colder regions within the same solid without bulk movement of the material.
