1. When benzene undergoes vaporization, it is changing from a liquid to a gas. This process occurs at the boiling point, where the temperature remains constant as the substance absorbs heat to change its state.
2. The letter on the graph that represents benzene undergoing vaporization is D. This is the plateau at the higher temperature where the substance is boiling.
3. The temperature of vaporization of benzene is 80°C. This is the temperature at which the substance boils and changes from a liquid to a gas.
4. The boiling point of benzene is 80°C. This is the temperature at which the substance changes from a liquid to a gas.
5. When benzene undergoes fusion, it is changing from a solid to a liquid. This process occurs at the melting point, where the temperature remains constant as the substance absorbs heat to change its state.
6. The letter on the graph that represents the melting of benzene is B. This is the plateau at the lower temperature where the substance melts.
7. The fusion point of benzene is 5°C. This is the temperature at which the substance melts and changes from a solid to a liquid.
8. It takes 10 seconds for benzene to undergo fusion. This is the time interval from the start of the melting process (point B) to the end of the melting process (the end of the plateau at point B).
