What are the possible research questions?

its a physical change as it changes matter from liquid to solid

# data[].attributes.body
I think its a chemical change because they are completely changing the molecular structure of the milk and vinegar, which is now plastic

# data[].attributes.body
this is a chemical process because you are using 2 solute to make a solid and you cant make that solid back to liquid because we have extracted protein from milk.

Chemical Change- The cream cheese made by him, will not become the separate milk and vinegar again. Because the milk has curdled.

# data[].attributes.body
It is a chemical change as the change from milk to fat or cheese is a chemical change. This is as milk has curdled and given out fat and protein.

# data[].attributes.body
I think it is a chemical change because you are taking 2 liquids and turning it into a solid but you cannot reverse that

# data[].attributes.body
i believe it is a chemical change because it is not reversible since you may be able to break down the solid but you can not get back milk and vinger

Question 1 -
I think it is a chemical change because it is shown that 2 liquids are becoming one solid.

# data[].attributes.body
Question 1- It's a chemical change because a new substance to make plastic was created by a chemical reaction between elements milk and vinegar.

# data[].attributes.body
I think this is a chemical change because you are taking 2 substances and changing the structure of the plastic

# data[].attributes.body
this is a chemical change because it is a mixture of two substances that creates another substance.

A research question is an inquiry into one specific thing you want to do.
