Part 2: Intensive vs. Extensive Properties. Compare the matter. Do they have the same extensive property or the same intensive property? Extensive properties define a quantity. Intensive properties define unique characteristics because of composition. On the line next to the item, • type I for intensive only • type E for extensive only • type B for both if there are common intensive and extensive properties type N for neither if there is no common intensive or extensive property. • Only type the letter. 13 14 15 16 17 18 19 20 21 22 A 10 kg granite rock and a 10 kg basalt rock. 50 liters of water and 20 liters of water. 40 grams of chalk and 30 grams of chalk. 1 kg basketball and 0.10 kg golf ball. 10 liters of hydrogen gas and 10 kg of air. 20 meters of rope and 20 meters of string. 50 grams of clear glass and 30 grams of clear plastic 100 kg human and 50 kg tree. 2 kg polyethylene helmet and 1 kg polyethylene knee pads 40 pounds of zinc and 40 pounds of iron.

Your breakfast this morning was so nutritious! You had two eggs, a slice of toast and some orange juice. You were lucky, though... your mom noticed some smoke coming from the toaster and took your toast out before it burned. Thanks to her, your toast was a perfectly crunchy and light-brown in color: During this process, did the bread undergo a physical change or a chemical change? What evidence from the story or the image proves that you are correct?

When large pieces of a purple-black crystalline solid are gently heated, a purple vapor is formed which upon cooling deposits many tiny purple-black crystals with the same hardness, density, reflectivity, etc. as the large pieces. Did this experiment study chemical changes or physical ones? Justify your answer with reasoning.
