A student weighs a piece of metal and finds that it is 4.4g. The student then holds this piece of metal with tongs and heats it using the flame of a Bunsen burner. After the final product is cooled, it is weighed and found to have a mass of 5.0g. Which of the following statements related to the experiment is correct?
a. The mass of the metal decreased due to the physical processes of melting/boiling.
b. The metal increased in temperature only and neither a physical or a chemical change occurred.
c. The mass of the metal increased when it went through a chemical change as bonds formed between the metal and another substance.
d. The metal was only heated and was unable to react with any substance so a physical change occurred
