Steam at $100^{\circ} \mathrm{C}$ is added to ice at $0^{\circ} \mathrm{C}$. (a) Find the amount of ice melted and the final temperature when the mass of steam is $10 \mathrm{~g}$ and the mass of ice is $50 \mathrm{~g}$, (b) Repeat with steam of mass $1.0 \mathrm{~g}$ and ice of mass $50 \mathrm{~g}_{\mathrm{t}}$

Key Concepts

Conservation of Energy in Thermal Processes

This principle states that energy in an isolated system remains constant. In thermal problems, it is used to set up energy balance equations that equate the energy lost by one component (such as condensing steam) to the energy gained by another (such as melting ice or warming water), ensuring that all energy exchanges are accounted for during phase transitions and temperature changes.

Specific Heat Capacity

Specific heat capacity is the measure of the energy required to raise the temperature of a unit mass of a substance by one degree Celsius. When substances do not undergo a phase change, this concept is used to calculate how much energy is needed for or released during temperature changes, and it complements phase change considerations in overall thermal energy balance.

Latent Heat of Vaporization

This term describes the energy required to convert a liquid into a gas at its boiling point, or vice versa, without a change in temperature. It is essential in problems involving steam because it determines the amount of energy released when steam condenses, which can then facilitate other thermal processes like melting ice.

Latent Heat of Fusion

This is the amount of energy required to change a substance from a solid to a liquid at its melting point without any change in temperature. In problems involving ice melting, it is the key concept that quantifies how much energy must be supplied to convert ice into water, central to understanding phase change energy calculations.
