Question

This is not English but help please.
So i have my hypothesis done i just need help on 3 simple questions.

Answer 1

Today you will be investigating how a change in temperature affects a gas inside of a container.
Hypothesis: What is the effect of temperature on the motion of particles?
Designing an Experiment After developing your hypothesis, the next step in the inquiry process is to design a controlled experiment in order to test your hypothesis. In a controlled experiment, all variables are kept constant except the one that you are testing. The variables you keep the same are called controlled variables. The variable that you change or test is called the manipulated variable. The variable that responds to changes you make is called the responding variable.
a. How would you design a controlled experiment to test the hypothesis you made about the volume of a gas?

b. What is the manipulated variable in your experiment?

c. What is the responding variable in your experiment?

Answer 2

can you help @Maddi8

Answer 3

i just need to fill a. b. and c. in

Answer 4

What was your hypothesis?

Answer 5

Hypothesis: What is the effect of temperature on the motion of particles?

Answer 6

my answer to my hypothesis is:
Thesis: temperature of the gas is directly a measure of kinetic energy of the molecule of the gas...So as temperature increases..Thus it increases the kinetic energy, thus increasing the spped of the molecules of gas. Now the increased speed causes an increase in the number of collisions and due to the increase in collisions, the pressure of the gas goes up. So equation goes like,
V1/V2=T1/T2
It states that at constant pressure, the amount of space a gas takes up will increase if the temperature rises and will decrease if the temperature is lowered. In short increasing the temperature will cause a gas to expand (increase the volume), and contract when cooled (decreasing the volume)....!! Again, if the volume is fixed, then increasing the pressure will increase the temperature, and decreasing the pressure will decrease the temperature. All these concepts are based on ideal gas equation.

Answer 7

A. you can test your hypothesis by filling up a balloon with air and then put each balloon under different temperatures and weigh them before and after each test.
B. The manipulated variable would be Testing to prove that the temperature can change the amount of gas present
C. The responding variable is weighing the balloons before and after the experiments.

Answer 8

Thank you @Maddi8 i really appreciate your time!

Answer 9

No problem(:

Answer 10

Based on a graph
A.Which measurement (with its units) is plotted on the x-axis?

b.Which measurement (with its units) is plotted on the y-axis?

c.At 350 K, what is the approximate volume?

D. What will be the approximate volume when the temperature is 900 K?
@Maddi8

Answer 11

Do you have the graph?

Answer 12

And right under the graph it has the 4 questions i listed above.@Maddi8

Answer 13

does that make since? @Maddi8

Answer 14

Yah hold on :)

Answer 15

Did you fill out the graph??

Answer 16

okay anything helps. its just that and im done. this is still about the same investigation from the begining and no i didnt. is there anyything i can just throw in there?

Answer 17

I don't know.. I would need numbers on the graph to answer your question, sorry!

Answer 18

this is what they have me doing

Answer 19

i just need to do #5 @Maddi8
