🔍 Key Concepts

• Heat transfer rate and how it depends on driving forces • Effect of temperature difference (ΔT) in conduction and convection • Difference between amount of heat stored vs. rate of heat flow

💭 Think About

• Ask yourself: which option directly changes how fast heat moves from hot to cold, not just how much heat exists? • Consider a pipe carrying hot fluid to a cooler space: what single factor, if made larger, obviously increases the flow of heat per second? • Think about the basic idea behind why better insulation works: which variable does insulation try to reduce in order to slow the rate of heat transfer?

✅ Before You Answer

• Identify which choice refers to a driving force rather than a capacity or size • Check which option would appear in the numerator of a basic heat-transfer rate formula (for example, in Fourier’s law or Newton’s law of cooling). • Verify that the option you pick affects the rate (per unit time), not just the total heat content of the system.
