🔍 Key Concepts

• Second Law of Thermodynamics and the natural direction of heat flow • Difference between hot and cold bodies in terms of energy • The idea of spontaneous vs. forced (refrigeration) heat transfer

💭 Think About

• Ask yourself: in everyday life, without any machines helping, which way does heat naturally move—toward hotter things or colder things? • Think about an ice cube in warm water: does the ice cube make the water colder, or does the water make the ice cube warmer—and which direction is the heat going? • Consider whether heat can naturally and continuously move both ways at the same time between hot and cold without outside work being done.

✅ Before You Answer

• Verify which option describes heat moving from hot to cold in a clear, one-way (uni-directional) manner under natural conditions • Eliminate any option that says heat naturally flows from cold to hot without work being applied (like in a refrigerator or heat pump) • Be careful with answers that suggest the direction of heat flow is unpredictable or bi-directional under normal, spontaneous conditions

Question 1 of 20

What statement represents the second law of thermodynamics?

When heat is transferred from one body to another, the direction of heat flow is uni-directional from the relatively cold body to the relatively hot body.

When heat is transferred from one body to another, the direction of heat flow between the two bodies is unpredictable.

When heat is transferred from one body to another, the direction of heat flow is uni-directional from the relatively hot body to the relatively cold body.

When heat is transferred from one body to another, the direction of heat flow is bi-directional from the relatively hot body to the relatively cold body and from the relatively cold body to the relatively hot body.
