What is the significance of the Second Law of Thermodynamics in everyday appliances?

• It ensures they operate without energy.

• It explains their energy efficiency limits.

• It makes them operate faster.

• It reduces their cost.

Why can't a heat engine be 100% efficient?

• A) Because the First Law of Thermodynamics states energy is always conserved.

• B) Because the Second Law of Thermodynamics states some energy is always lost as waste heat.

• C) Because the Third Law of Thermodynamics states absolute zero is unattainable.

• D) Because the Zeroth Law of Thermodynamics states thermal equilibrium is necessary.
