Boiling Point Calculator

How to Use the Boiling Point Calculator

This step-by-step guide explains how to use the Boiling Point Calculator to determine the boiling point of various substances based on atmospheric pressure and altitude.

Step 1: Provide Atmospheric Pressure

Begin by inputting the atmospheric pressure in kilopascals (kPa) into the designated field. Make sure that the value you enter is within the valid range of 0.1 to 1000 kPa. This input is mandatory, and you can adjust the value in increments of 0.1 kPa.

Step 2: Enter Altitude

Next, input the altitude above sea level in meters. The valid range for the altitude is between -500 to 9000 meters. Like the pressure field, this input is required, and the value should be entered in whole numbers, with a step of 1 meter.

Step 3: Select the Substance

Choose the substance for which you want to calculate the boiling point from the dropdown menu. The available options are:

• Water (H₂O)
• Ethanol (C₂H₅OH)
• Methanol (CH₃OH)
• Acetone (C₃H₆O)

Selection of the substance is required for further calculations.

Step 4: Review Results

Once all the necessary inputs are provided, the calculator will display the following results:

• Standard Boiling Point (°C): This is calculated using the known standard boiling points for the selected substance:
• Water: 100°C
• Ethanol: 78.37°C
• Methanol: 64.7°C
• Acetone: 56.05°C
• Pressure-Adjusted Boiling Point (°C): This adjusts the standard boiling point based on the entered atmospheric pressure.
• Altitude-Adjusted Boiling Point (°C): This result modifies the pressure-adjusted boiling point by accounting for the given altitude.
• Boiling Point (°F): This is the final boiling point after all adjustments, presented in Fahrenheit.

Each result is formatted to two decimal places for precision.
