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.

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. |
