A biology experiment requires the preparation of a water bath at 37.0°C (body temperature). The temperature of the cold tap water is 22.0°C, and the temperature of the hot tap water is 55.0°C. If a student starts with 90.0. g of cold water, what mass of hot water must be added to reach 37.0°C?

Transcribed Image Text:**Experiment Preparation: Water Bath Temperature Problem**
A biology experiment requires the preparation of a water bath at 37.0°C (body temperature). The temperature of the cold tap water is 22.0°C, and the temperature of the hot tap water is 55.0°C. If a student starts with 90.0 g of cold water, what mass of hot water must be added to reach 37.0°C?
**Concept Explanation:**
This problem involves the concept of mixing water at different temperatures to achieve a desired final temperature. To solve this, we can use the principle of heat transfer, where the heat lost by the hot water will equal the heat gained by the cold water until thermal equilibrium is reached.
