In this diagram, heat energy is being added over time. The vertical axis shows an increase in temperature, and the horizontal axis shows the passage of time.

What is happening to the temperature at Point B? 

• The temperature is not rising because the heat is being used to break the connections between the molecules.

• The temperature is not rising because the molecules are slowing down.

• The temperature is rising as the molecules break apart from each other.

• The temperature is dropping as the molecules break apart from each other.

In this diagram, heat energy is being added over time. The vertical axis shows an increase in temperature, and the horizontal axis shows the passage of time. In the diagram, the solid eventually becomes a gas.

What will happen to bring the substance from a solid to a gas? 

• Energy will be taken away.

• Energy will be added.

• • 
    

    The substance will lose pressure.

• The substance will lose volume.
