Multiple Choice

Which properties best describe an egg?

• Chemical Change

• None of the above

Multiple Choice

Which is an example of Physical Change?

• wood turns to charcoal

• water freezes to ice

• naphthalene balls turn to vapor

• grilling of pork

Multiple Choice

Physical change happens when materials undergo a change in...

• size

• phase

• shape

• all of the above

Multiple Choice

Which statement is true about Physical Change?

• It does not change a materials composition

• It does not change a materials size and shape

• It does not involve the physical properties of matter

• It does not involve in matter

Multiple Choice

Which is an example of  Physical Change?

Multiple Choice

Which process involves a Physical Change?

​Water cycle is a physical change as it involves the transformation of H2O into its three states. No chemical reaction takes place during the whole process. It's reversible as water after evaporating and forming the clouds again precipitate to come down as water again.

Multiple Choice

Burning a match is an example of a ___________

• chemical change

• physical change

Multiple Choice

An example of a Physical Change

• foam and bubbles form after mixing baking soda and vinegar

• a glass cup falls from the counter and shatters on the ground

• paper burns up leaves ashes

• a plant uses sunlight and makes food

Multiple Choice

Which is true about Chemical Change?

• It is reversible

• It produces new materials

• It changes only a material's color and odor

• It does not change a material's size and shape

A chemical change is permanent. It means that the newly formed substances cannot be easily changed back to the parent compounds by simply changing the physical conditions of a reaction. Hence, a chemical change is irreversible or permanent.​

• ​Rusting of iron in presence of moisture and oxygen.

• Burning of wood.

• Milk becoming curd.

• Formation of caramel from sugar by heating.

• Baking of cookies and cakes.

• Cooking any food.

• Acid-base reaction.

• Digestion of food.

Multiple Choice

An example of Chemical Change is

Multiple Choice

Which shows a chemical change?

Multiple Choice

It is the PRIMARY cause of rust because it contains oxygen

• carbon dioxide

• water

• air

• hydrogen

​The PRIMARY cause of rust because it contains oxygen and water.

​Rust is the result of a natural process where the iron in metals comes into contact with oxygen and water, causing it to corrode and deteriorate. When they combine, it is called oxidation and the chemical reaction produced causes ferric oxide to form – rust.

Multiple Choice

Rusting iron made materials is commonly caused by the _________

• presence of heat

• absence of heat

• presence of oxygen

• absence of oxygen

Multiple Choice

What change takes place when a fruit starts to rot?

• chemical change

• no change

• physical change

• physical property

Multiple Choice

Which is NOT true in the statement below?

• burning a paper involves a presence of heat

• cutting a banana in half is an example of physical change

• melted candle is a form of chemical change

• freezing a water is a form of physical change

Multiple Choice

What change will happen if you slice an apple and expose?

• color will change from brown to white

• color will change from white to brown

• the color will not change

• no changes in color

Multiple Choice

Kimberly wiped the top of the table with a wet piece of cloth. After a few minutes, it became dry. Why does the table dry up so quickly?
