But making this mixture does not form a different type of matter. Water vapor condensing on a bathroom mirror is a change of state. So, it is a physical change. The water changes state from gas in the air to liquid water on the mirror. But the water vapor and the liquid water are both made of water. Step 2: Look at each answer choice. Both are only physical changes. Both changes are physical changes. No new matter is created. Both are chemical changes. Both changes are physical changes. They are not chemical changes. Both are caused by heating. Neither change is caused by heating. Both are caused by cooling. Water vapor condensing is caused by cooling. But mixing lettuce and salad dressing is not.

What do these two changes have in common? a piece of avocado turning brown burning a marshmallow over a campfire

[ "Both are only physical changes.", "Both are caused by cooling.", "Both are chemical changes.", "Both are caused by heating." ]

C

Step 1: Think about each change. A piece of avocado turning brown is a chemical change. The avocado reacts with oxygen in the air to form a different type of matter. If you scrape off the brown part of the avocado, the inside will still be green. The inside hasn't touched the air. So the chemical change hasn't happened to that part of the avocado. Burning a marshmallow is a chemical change. The heat from the fire causes the type of matter in the marshmallow to change. The marshmallow becomes black and crispy. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Burning is caused by heating. But a piece of avocado turning brown is not. Both are caused by cooling. Neither change is caused by cooling.

H is the symbol for hydrogen. According to the legend, hydrogen atoms are shown in light gray. O is the symbol for oxygen. According to the legend, oxygen atoms are shown in red. This ball-and-stick model shows a molecule with two hydrogen atoms and one oxygen atom. The chemical formula will contain the symbols H and O. There are two hydrogen atoms, so H will have a subscript of 2. There is one oxygen atom, so O will not have a subscript. The correct formula is H2 O.

What do these two changes have in common? compost rotting chicken cooking in an oven

[ "Both are chemical changes.", "Both are only physical changes.", "Both are caused by cooling.", "Both are caused by heating." ]

A

Step 1: Think about each change. Compost forms from the remains of plants and animals, such as vegetable scraps and egg shells. Compost rotting is a chemical change. As the compost rots, it breaks down and turns into a different type of matter. Cooking chicken is a chemical change. The heat causes the matter in the chicken to change. Cooked chicken and raw chicken are different types of matter. Step 2: Look at each answer choice. Both are only physical changes. Both changes are chemical changes. They are not physical changes. Both are chemical changes. Both changes are chemical changes. The type of matter before and after each change is different. Both are caused by heating. Cooking is caused by heating. But compost rotting is not. Both are caused by cooling. Neither change is caused by cooling.
