How do scientists use the kinetic theory of matter?

Question

Which one is right

• They use it to explain the shape of matter

They use it to study the effect of time on matter

They use it to explain the color of matter.

• They use it to study the effect of energy on matter.

Answer 1

The correct answer is: They use it to study the effect of energy on matter.

Scientists use the kinetic theory of matter to understand how energy affects the behavior and properties of different forms of matter. This theory states that all particles in matter are in constant motion, and their movement increases with added energy. By studying how energy influences the motion, temperature, and other properties of particles, scientists can better understand the behavior of matter and make predictions about its physical properties in various conditions.

Answer 2

There are 40 students in Joan’s class. She plans to invite them to her birthday party. She asked them to suggest a theme for her party. Three of every eight students suggested a rainbow-themed party. How many students suggested a rainbow-themed party? How many did not?(2 points) Suggested Rainbow Did not suggest Rainbow

Answer 3

To find out how many students suggested a rainbow-themed party, we can use the information that three out of every eight students suggested this theme.

First, we can find out how many students are in groups of eight.
40/8 = 5

Since each group of eight represents the number of students that made suggestions, we know that there are 5 groups of eight.

To find out how many students suggested a rainbow-themed party, we can calculate 3 students per group of eight.
3 x 5 = 15 students

Therefore, 15 students suggested a rainbow-themed party.

To find out how many students did not suggest a rainbow-themed party, we can subtract the number of students who did suggest it from the total number of students.
40 - 15 = 25 students

Therefore, 25 students did not suggest a rainbow-themed party.
