I truly don't understand how a graph of this would look. I did the 2nd part of this assignment but I don't know how to do this part... Is there anyways someone can give a physical example or graph of this.
Dr. Wong's assistant made the observations below while heating a sample of solid hydrogen. Using the data and observations in the table below, create a heating curve for hydrogen that Dr. Wong can reference during his laboratory testing. Be sure to include and label the following items in your heating curve:
Create temperature and time intervals that are appropriate for the data.
Don't start the temperature on the graph at 0 °C because the time intervals will be too large for the hydrogen data.
Label the melting and boiling points on the curve.
Label the three states and the two transition phases on the curve.
Heating data:
Time (Minutes) Observations
0:00 Hydrogen is a solid at −263 °C. Heat is added to sample.
2:43 Hydrogen begins to change into a liquid at −259 °C.
6:15 Temperature of the liquid begins to increase.
10:36 Hydrogen begins to form a gas at −253 °C.
14:01 Temperature of the gas begins to increase.
18:00 Final temperature of hydrogen gas is −245 °C.

Heating Curve for Hydrogen
**Y-axis:** Temperature (°C) - Range from -265 °C to -240 °C
**X-axis:** Time (minutes) - Range from 0 to 20 minutes
**Curve:**
1. **Start at point (0, -263):** This represents solid hydrogen at -263 °C. Label this section of the graph as "Solid."
2. **Horizontal line from (0, -263) to (2.43, -263):** This shows the heating of the solid without a change in temperature.
3. **Vertical line from (2.43, -263) to (2.43, -259):** This represents the melting of hydrogen at -259 °C. Label this point as "Melting Point." Label the section between the vertical lines as "Solid + Liquid."
4. **Horizontal line from (2.43, -259) to (6.15, -259):** This shows the complete melting of solid hydrogen into liquid. Label this section as "Liquid."
5. **Diagonal line from (6.15, -259) to (10.36, -253):** This represents the heating of liquid hydrogen.
6. **Vertical line from (10.36, -253) to (10.36, -253):** This represents the boiling of hydrogen at -253 °C. Label this point as "Boiling Point." Label the section between the vertical lines as "Liquid + Gas."
7. **Horizontal line from (10.36, -253) to (14.01, -253):** This shows the complete vaporization of liquid hydrogen into gas. Label this section as "Gas."
8. **Diagonal line from (14.01, -253) to (18, -245):** This represents the heating of hydrogen gas.
9. **End at point (18, -245):** This represents the final temperature of the hydrogen gas.
