Objective 6: Ice, water, and the entropy balance
Before you begin
Your goal: Predict how much ice melts when it contacts warmer water, calculate the entropy change of each original portion, and use their sum to assess the direction of the process.
Work from heat and phase-change fundamentals toward a complete energy and entropy balance. All data for this original example are supplied within the activity.
- Read each question and write your answer and reasoning on paper or in your own notes.
- Keep your original answer intact. Do not erase or overwrite it.
- Switch on “Reveal answer,” then separately record what you got right, what you got wrong, and what you left out.
- Rewrite your answer underneath the original, staying as faithful as possible to your own wording while making the necessary corrections and additions.
- Finish your reflection and rewrite, then select “Next question.” Earlier questions collapse and can be reopened. The “Compare, then revise” reminder is available inside each answer. The Key connections sidebar grows as you reveal answers.

About this estimate
Plan for 65–95 minutes. This includes working through all 14 questions, writing your answers separately, comparing and revising them, and completing the independent ice–water practice problem. The estimate assumes brief responses without outside research. This is a planning estimate; your pace may vary.
Your answers stay in your own notes. This page does not collect responses or save progress. Reloading starts the lesson again.
