A student filled four different bowls with 10 ice cubes in each. Each bowl was the same size and shape. The student timed how long it took all the ice cubes in each bowl to melt. The results are shown above.

Based on these data, what should the student conclude?

• The metal bowl is the best conductor.

• The plastic bowl is the most flexible.

• The clay bowl is the hardest bowl.

• The glass bowl is easiest to break.
