Explanation

• A heat engine works between a hot source and a cold sink.
• Efficiency depends on the temperature difference between them.
• Greater the difference, higher the efficiency.
• Maximum efficiency is given by Carnot engine.

Explanation

• A standing wave is formed by the interference of two waves of equal frequency and amplitude.
• Nodes are fixed points where particles do not move.
• At these points, displacement remains zero at all times.
• Energy transfer at nodes is minimum.

Explanation

• Boyle’s Law describes the relationship between pressure and volume.
• At constant temperature, gas behaves in a specific way.
• Pressure increases when volume decreases.
• Pressure decreases when volume increases.
• Formula: P₁V₁ = P₂V₂

Explanation

• Bohr’s model states that electrons move in fixed energy levels (shells).
• These paths are also called orbits or stationary states.
• Each orbit has a definite energy.
• Electrons do not lose energy in these orbits.
