In an energy recycling process, $X g$ of steam at $100^{\circ} \mathrm{C}$ becomes water at $100^{\circ} \mathrm{C}$ which converts $Y \mathrm{~g}$ of ice at $0^{\circ} \mathrm{C}$ into water at $100^{\circ} \mathrm{C}$. The ratio of $X / Y$ will be : (a) $\frac{1}{3}$ (b) $\frac{2}{3}$ (c) 3 (d) 2

Key Concepts

Energy Conservation in Phase Change Processes

This principle asserts that the energy released by one process must be equal to the energy absorbed by another when no energy is lost to the surroundings. This concept allows us to set up energy balance equations when dealing with multiple simultaneous phase changes and temperature changes.

Latent Heat

This is the amount of energy per unit mass required to change the phase of a substance at a constant temperature. It plays a critical role in processes where substances absorb or release energy without changing their temperature, such as in evaporation, condensation, fusion (melting), or freezing.

Latent Heat of Condensation

This is the energy released per unit mass when a vapor condenses into a liquid at a constant temperature. In energy transfer problems, it is important because the energy given off during condensation can be used to drive other processes, such as melting ice or heating water.

Latent Heat of Fusion

This represents the energy absorbed per unit mass when a substance changes from solid to liquid at its melting point. It is crucial for calculating the energy needed to melt a solid, like ice, without changing its temperature during the phase transition.

Specific Heat Capacity

This is the energy required per unit mass to raise the temperature of a substance by one degree Celsius. In problems involving heating or cooling, after a phase change has occurred, specific heat capacity is used to determine the energy needed to achieve a desired temperature change.
