Question

Planet Average Surface
Temperature (K) Average Orbital
Velocity (km/s)
Mercury 440 47.87
Venus 737 35.00
Earth 288 29.78
Mars 208 24.13
Jupiter 163 13.07
Saturn 133 9.69
Uranus 78 6.81
Neptune 73 5.43

Use the data table above to describe the relationship between average surface temperature and average orbital velocity (how fast they orbit) of the planets of our solar system. Use numerical data from the table to support your answer.

Answer 1

I'm sorry, this graph is much easier to understand:

Planet Average Surface
Temperature (K) Average Orbital
Velocity (km/s)
Mercury 440 47.87
Venus 737 35.00
Earth 288 29.78
Mars 208 24.13
Jupiter 163 13.07
Saturn 133 9.69
Uranus 78 6.81
Neptune 73 5.43

Answer 2

increasing temperature correlates in increasing orbital velocity

Answer 3

Okay, but how numerically?

Answer 4

what do you mean how numerically? :/

Answer 5

Well it says "provide numerical data from the table to support your evidence"? aha

Answer 6

Planet Temp (K) Orbital Velocity (km/s)

Mercury 440 47.87
Venus 737 35
Earth 288 29.78
Mars 208 24.13
Jupiter 163 13.07
Saturn 133 9.69
Uranus 78 6.81
Neptune 73 5.43

This seems a little bit better

Answer 7

Yeah, much better. I'm too lazy for that ;)

Answer 8

I like to try messing around with that sort of thing.

Answer 9

@alias Do you understand what it means? Because I don't..

Answer 10

I imagine they want a formula to show some relationship between temperature and orbital velocity

Answer 11

It's just a coincidence that orbital velocity corresponds to temperature. (Obviously the slower a planet travels, the colder it will be.)

Answer 12

Ohh okay. Do you know how to get it? I'm terrible at both Math and Science. Language and History are my better subjects :D

Answer 13

I don't think you're supposed to come up with functions and things like that. They're just asking for a qualitative statement

Answer 14

I'd imagine it is impossible to get an exact formula.
Basically there is an inverse relationship between temp and orbital velocity
temp α 1/orbital velocity
(the α is the Greek lower case alpha)

Answer 15

and @AshB haha, I'm hopeless in Language and History

Answer 16

I mean, you can input the data in excel and get the slope, and by that say that since the slope is positive, the two is directly proportional

Answer 17

quick inverse relationship definition:
an increase in one thing produces a decrease in another
example:
the more you weigh, the slower you will run.

Answer 18

but I believe by "numerical data," the question just ask for your observation (no function is needed). So just say that according to the data from the table, there is evidence suggesting that surface temperature and orbital velocity is proportional

Answer 19

Tbh, what you two are saying almost seems like a foreign language hahah. I promise I'm not as dumb as I sound ;D but is there anyway I could get a really easy way to find it out or just get the answer?

Answer 20

it's not inversely proportional... just proportional. Because inversely proportional would mean that as one increases, the other decreases (not true in problem)

Answer 21

No wait - it IS proportional ---- SORRY !!!

Answer 22

I'm deleting my previous comment

Answer 23

and to rewrite my equation
temp α orbital velocity
temperature is proportional to orbital velocity

Answer 24

So the answer would just be 'Temperature is proportional to orbital velocity'?

Answer 25

yea

Answer 26

Oh, okay. Thank you both a lot for your help :)

Answer 27

and you could compare some planets with each other, and use that as examples for "numerical data"

Answer 28

Okay, what would be an example of that?

Answer 29

I just made a graph:

Answer 30

Oh, okay! Thanks, this helps a lot

Answer 31

I neatened the graph up just a bit:

Answer 32

Nice! Thanks again

Answer 33

u r welcome
oh and it is a DIRECT RELATIONSHIP between temp and orbital velocity
(still can't believe how I messed that up earlier)

Answer 34

and the correct formula is:
temp α orbital velocity

Answer 35

I came to the same conclusion for this question for someone else,
noting a fairly constant ratio Temp/vel
