I got a 100%
Great job! Your answers are correct. A chemical change is when the chemical makeup of a substance is changed, creating a new substance. A physical change, on the other hand, does not change the chemical makeup of a substance, but only its physical properties. Keep up the good work!
Great job, you got both questions correct! The first question asked you to identify the type of change that occurred in different scenarios, and you correctly identified them as physical or chemical changes. The second question asked you to determine which type of change involves a change in the chemical makeup of a substance, and you correctly answered that it is a chemical change. Well done on getting a perfect score!
Great job on getting a perfect score! Let's go over the answers together:
1. The first question asks you to identify the type of change that occurred in different scenarios. Here are the correct answers for each scenario:
- Lemons, water, and sugar combined in a pitcher to form sweet lemonade drink: This is a Physical Change because the substances (lemons, water, and sugar) are just mixed together without any chemical reaction taking place.
- Eggs, flour, sugar, and butter combined then baked to make crispy and warm cookies: This is a Chemical Change because when the ingredients are baked, the chemical makeup of the substances changes, resulting in the formation of a new substance (cookies).
- Melting butter to mix in with cream to make rich and creamy buttercream frosting: This is a Physical Change because the butter is changing from a solid to a liquid state without any chemical reaction occurring.
- Dissolving several sugar cubes and adding milk to a hot cup of tea to make a sweet tea beverage: This is also a Physical Change because the sugar cubes are dissolving in the hot liquid (tea and milk), but no new chemical substances are formed.
2. The second question asks you to determine the correct definition of a chemical change. The correct answer is "A change in the form of matter in which the chemical makeup of the substance is changed, creating an entirely new substance." This definition describes a chemical change, where the original substances are transformed into new substances with different properties.
