Accepted Answer

∻Solution∻ ‖ 1 ⋮ **Understand the concept**: The boiling point of a liquid is the temperature at which its vapor pressure equals the external pressure. ‖ ‖ 2 ⋮ **Use the phase diagram**: A phase diagram can be used to determine the boiling point of water at different pressures. The given pressure is $0.79 \mathrm{~atm}$. ‖ ‖ 3 ⋮ **Read the diagram**: If the figure provided is a phase diagram of water, locate the line that represents the vaporization curve and find the point where it intersects with $0.79 \mathrm{~atm}$. The temperature at this point is the boiling point of water under the given pressure. ‖ ‖ 4 ⋮ **Determine the boiling point**: Without the actual figure, we cannot determine the exact boiling point. However, based on typical phase diagrams and the given options, the boiling point of water at $0.79 \mathrm{~atm}$ would likely be lower than $100^\circ C$ (the boiling point at $1 \mathrm{~atm}$) and higher than the boiling point at higher altitudes (where pressure is significantly lower). ‖ ∻Answer∻ ⚹ The boiling point of water under an external pressure of $0.79 \mathrm{~atm}$ is likely to be 70°C, assuming the typical behavior of water's phase diagram. ⚹ ∻Key Concept∻ ⚹ Boiling point and external pressure relationship ⚹ ∻Explanation∻ ⚹ The boiling point of water decreases as the external pressure is reduced from standard atmospheric pressure. ⚹◊What is the relationship between external pressure and boiling point in the context of water?⍭ Generate me a similar question◊
