Deshawn is conducting an experiment about fermentation. He prepares six bottles. The table shows what he puts in each bottle.

bottle 1 1 cup cold water, 1 packet yeast
bottle 2 1 cup cold water, 1 packet yeast, 2 tablespoons sugar
bottle 3 1 cup lukewarm water, 1 packet yeast
bottle 4 1 cup lukewarm water, 1 packet yeast, 2 tablespoons sugar
bottle 5 1 cup hot water, 1 packet yeast
bottle 6 1 cup hot water, 1 packet yeast, 2 tablespoons sugar
He swirls the bottles until the yeast dissolves and puts a balloon over the neck of each bottle. In 20 minutes, he will check and see what has happened.

Will want to explore these changes in more depth, so we compare two kinds of ways matter changes and how they differ. He recorded his phonics in a science notebook. What are the ways in which matter changes, and how do they differ?

Answers

Answer: There are two types of change in matter: physical change and chemical change.

Explanation:

As the names suggest, physical changes never change the identity of the matter, only its size, shape or state. In a physical change, atoms are not rearranged and the matter's physical and chemical properties are unchanged.

to learn more about matter and how it changes take a look at this website:

https://en.wikibooks.org/wiki/General_Chemistry/Properties_of_Matter/Changes_in_Matter#:~:text=There%20are%20two%20types%20of,and%20chemical%20properties%20are%20unchanged.

Victoria and her teacher measured a sample of matter in the science lab. They measured the sample using all of the tools below to make sure the results were correct.

Each time they measured the sample, its shape changed to match the shape of the container. The amount of the sample always equaled 400 mL.

What type of matter did Victoria and her teacher measure?

A. gas

B. liquid

C. solid

Answers

Answer:

The answer  is liquid

Explanation:

Because liquid is a type of matter that does not have a definitive shape, so it relies on taking its shape from the substances that it settles in.

In this example, the amount of liquid used was 400mL, when they poured liquid in, it took the shape of the container.

While gas can get a shape of a container, its volume is not fixed.

Answer: Your correct the answer is liquid
