scienceQA-9729	multiple_choice	What do these two changes have in common? compost rotting cooking an egg	[ "Both are caused by cooling.", "Both are chemical changes.", "Both are only physical changes.", "Both are caused by heating." ]	B	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 an egg is a chemical change. The heat causes the matter in the egg to change. Cooked eggs and raw eggs are made of 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.

This creates electricity, which powers the lightbulb. 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. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.

Which of the following organisms is the secondary consumer in this food web?

[ "beaver", "bobcat", "persimmon tree", "swallowtail caterpillar" ]

B

Secondary consumers eat primary consumers, and primary consumers eat producers. So, in a food web, secondary consumers have arrows pointing to them from primary consumers. Primary consumers have arrows pointing to them from producers. The black racer has an arrow pointing to it from the pine vole. The pine vole is a primary consumer, so the black racer is a secondary consumer. The beaver has an arrow pointing to it from the silver maple. The silver maple is not a primary consumer, so the beaver is not a secondary consumer. The persimmon tree does not have any arrows pointing to it. So, the persimmon tree is not a secondary consumer. The swallowtail caterpillar has an arrow pointing to it from the persimmon tree. The persimmon tree is not a primary consumer, so the swallowtail caterpillar is not a secondary consumer. The bobcat has an arrow pointing to it from the beaver. The beaver is a primary consumer, so the bobcat is a secondary consumer.

What do these two changes have in common? rust forming on a metal gate making jam

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

B

Step 1: Think about each change. Rust forming on a metal gate is a chemical change. As the gate rusts, the metal turns into a different type of matter called rust. Rust is reddish-brown and falls apart easily. Making jam is a chemical change. It involves mixing fruit, sugar, and a substance called pectin. When these ingredients are mixed and cooked, the chemical bonds in their molecules are broken. The atoms then link together to form different molecules that make up the jam. 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. The reaction that makes jam is caused by heating. But rust forming on a metal gate is not. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? cellular respiration chemicals in a battery reacting to power a flashlight

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

C

Step 1: Think about each change. Cellular respiration is a chemical change. Cells use oxygen to break down sugar. Breaking the chemical bonds in sugar molecules releases energy that a cell can use. The atoms from the broken molecules then combine to form different molecules such as carbon dioxide and water. These molecules are different types of matter than sugar and oxygen. Chemicals in a battery reacting to power a flashlight is a chemical change. When the flashlight is turned on, the chemicals in the battery react with each other to form new chemicals. This creates electricity, which powers the lightbulb. 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. Neither change is caused by heating. Both are caused by cooling. Neither change is caused by cooling.
