A sample of steam with a mass of 0.552 $\mathrm{g}$ and at a temperature of $100^{\circ} \mathrm{C}$ condenses into an insulated container holding 4.25 $\mathrm{g}$ of water at $5.0^{\circ} \mathrm{C}$ . Assuming that no heat is lost to the surroundings, what is the final temperature of the mixture?

Key Concepts

Phase Change

Phase change refers to the transformation of a substance from one state of matter to another, such as from vapor to liquid. During phase changes, energy is exchanged in the form of latent heat without altering the temperature of the substance, playing a critical role in thermal calculations involving condensation or melting.

Latent Heat

Latent heat is the amount of energy absorbed or released by a substance during a phase change without a change in temperature. In thermal processes, particularly during condensation or vaporization, latent heat quantifies the energy involved in the phase transition and is crucial for calculating energy exchanges in a system.

Specific Heat Capacity

Specific heat capacity is the energy required to raise the temperature of a unit mass of a substance by one degree. It is a key property used in calorimetry to determine how different substances respond to heat transfer, especially when mixing substances of varying temperatures.

Calorimetry

Calorimetry is the technique of measuring the amount of heat exchanged during physical or chemical processes. By applying principles of energy conservation, calorimetry allows one to calculate changes in temperature when substances at different initial temperatures are mixed in an insulated system.

Energy Conservation

Energy conservation is the principle that energy cannot be created or destroyed but only transformed from one form to another. In thermal interactions, this principle is used to set up equations where the heat lost by one part of the system equals the heat gained by another, ensuring that the total energy of the system remains constant.
