Final answer:
The elevation of the rain-snow line at Whistler Mountain cannot be determined with just an 85-kPa pressure map; more data is required. Estimating such elevations would typically involve atmospheric pressure and temperature information. Meanwhile, questions regarding the atmospheric pressure based on boiling points at specific altitudes involve physics principles.
Step-by-step explanation:
The student's question regarding the elevation of the rain-snow line at Whistler Mountain using an 85-kPa pressure map cannot be answered directly without additional context or data. The elevation of the rain-snow line (also known as the snowline) depends on various factors including temperature, precipitation patterns, and atmospheric pressure. The provided information from a pressure map alone is not sufficient to determine the elevation of the rain-snow line. Normally, to determine this, one would use a combination of temperature data and pressure readings to estimate the altitude at which the temperature is at the freezing point.
In contrast, questions about atmospheric pressure at specific elevations where water boils at certain temperatures, such as in the high Andes or on Mt. Everest, fall within the realm of physics because they involve the relationship between boiling point, atmospheric pressure, and altitude. These can be resolved using the Clausius-Clapeyron relation or by referencing empirical data in published tables or boiling point elevation charts specific to different altitudes.
