Ice melting in a cup is a change of state. So, it is a physical change. The solid ice becomes liquid, but it is still made of water. The links between atoms in the water molecules do not change. So, a different type of matter is not formed. Pouring milk on oatmeal is a physical change. The oatmeal and milk form a creamy mixture. But making this mixture does not form a different type of matter. 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. Ice melting is caused by heating. But pouring milk on oatmeal is not. Both are caused by cooling. Neither change is caused by cooling.

What do these two changes have in common? compost rotting burning a piece of wood

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

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. Burning a piece of wood is a chemical change. When the wood burns, the type of matter in it changes. The wood turns black and gives off smoke. 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 compost rotting is not. Both are caused by cooling. Neither change is caused by cooling.

[ "Arctic fox", "mushroom", "grizzly bear", "lichen" ]

A

Use the arrows to follow how matter moves through this food web. For each answer choice, try to find a path of arrows to the earthworm.There is one path matter can take from the Arctic fox to the earthworm: Arctic fox->earthworm. mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the mushroom to the earthworm.. grizzly bear. The only arrow pointing from the grizzly bear leads to the mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the grizzly bear to the earthworm.. lichen. The only arrow pointing from the lichen leads to the barren-ground caribou. There are two arrows pointing from the barren-ground caribou to other organisms. One arrow points to the grizzly bear. The only arrow pointing from the grizzly bear leads to the mushroom. The other arrow pointing from the barren-ground caribou leads to the mushroom. No arrows point from the mushroom to any other organisms. So, in this food web, matter does not move from the lichen to the earthworm.. There is one path matter can take from the rough-legged hawk to the earthworm: rough-legged hawk->earthworm.

What do these two changes have in common? ice melting in a cup pouring milk on oatmeal

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

A

Step 1: Think about each change. Ice melting in a cup is a change of state. So, it is a physical change. The solid ice becomes liquid, but it is still made of water. The links between atoms in the water molecules do not change. So, a different type of matter is not formed. Pouring milk on oatmeal is a physical change. The oatmeal and milk form a creamy mixture. But making this mixture does not form a different type of matter. 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. Ice melting is caused by heating. But pouring milk on oatmeal is not. Both are caused by cooling. Neither change is caused by cooling.
