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.

To draw a heating curve include the temperatures in the observation as well as state changes (solid-liquid-gas)

What is a heating curve?

A heating curve is a type of graph that shows how substances change when exposed to constant heat. This often includes not only a change in temperature but also changes in the state.

Moreover, if a change in the state occurred this is due to the boiling point (temperature in which the substance changes from liquid to gas) and the melting point (temperature in which the substance changes from solid to liquid)

Here is the graph based on the information:

Time (Minutes)Observations

0:00 Hydrogen is a solid at −263 °C. Heat is added to the 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.
