Which of the following conditions must exist for heat to flow from one object to another?

Question 1 of 27070

Which of the following conditions must exist for heat to flow from one object to another?

🔍 Key Concepts

• Heat transfer and what it means for energy to move from one object to another • Difference between temperature and size/weight of an object • Types of heat transfer: conduction, convection, radiation

💭 Think About

• Ask yourself: what is the basic driving force that makes heat move from one object to another? • Can heat move between objects that are not touching? Think about the sun and the Earth. • Does being heavier or larger automatically mean something will transfer more heat, or is there another property that matters more?

✅ Before You Answer

• Verify which option mentions a difference in a property that directly relates to heat energy. • Check whether physical contact is always necessary for heat transfer, using examples from everyday life. • Eliminate options that focus on size or weight, and focus on what actually causes heat to flow.
