Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes developing a hypothesis. hint: to develop a hypothesis, you use logic and research to propose a possible explanation. luna was a deejay who used a bubble machine at her events. she wanted to know how to make the bubbles last longer. she read in a book that bubbles burst because the liquid that makes up the bubbles evaporates. she knew that warm liquids evaporate faster than cold liquids. so, luna expected that the temperature of the bubble solution could affect how long the bubbles lasted, with colder bubbles lasting longer. luna heated six bottles of bubble solution to 110°f, kept six bottles at 75°f, and cooled six bottles to 40°f, and then she measured how long bubbles from each of the bottles lasted. because the bubbles from the colder solution lasted longer than bubbles from the other solutions, luna reasoned that temperature does affect bubble lifespan. for her next deejay event, she iced the bubble solution before she loaded it into the bubble machine.

Explanation:

A hypothesis is a proposed explanation. Luna used her knowledge about liquid evaporation and temperature - warm liquids evaporate faster than cold ones - to propose that the temperature of the bubble solution could affect how long the bubbles lasted, with colder bubbles lasting longer. This is the part where she developed a hypothesis.

Answer:

So, Luna expected that the temperature of the bubble solution could affect how long the bubbles lasted, with colder bubbles lasting longer.
