Question

What do these two changes have in common?

sewing an apron
rain forming in a cloud
Select all that apply.
Both are changes of state.
Both conserve mass.
Both result in a different type of molecule than
was there before.
Both involve chemical bonds breaking.

Answer 1

Sewing an apron and rain forming in a cloud both conserve mass and do not involve the breaking of chemical bonds. They are both physical changes that do not result in new types of molecules.

Step-by-step explanation:

The student's question compares two processes: sewing an apron and rain forming in a cloud. These processes are fundamentally different in nature, but if we narrow down the selection to identify common aspects based on the principles of physical change, conservation of mass, and chemical bonds, we can provide meaningful answers.

• Both sewing an apron and rain forming in a cloud conserve mass. This means that when these changes occur, there is no loss or gain in the total mass of the materials.
• Neither process results in the formation of a different molecule than what was there before.
• Neither process involves the breaking of chemical bonds, as sewing an apron is a manual process of attaching fabric together without altering its molecular structure, and rain forming in a cloud is a physical state change from gaseous water vapor to liquid water.
