Question

100K=.85m3
150K=1.27m3
200K=1.7m3
250K=2.12m3
300K=2.54m3
350K=2.97m3
400K=3.39m3

What is the relationship between the temperature and the volume?

what will the approximate volume be at 1273.15K?

Answer 1

Do you see a pattern between temperature and volume?

Answer 2

no, i tried adding, subtracting, all that, my parents even tried to help but we don't know.

Answer 3

The temperature from 100K to 150K to 200K to 250K.
Is it increasing or decreasing?
K is Kelvins.

Answer 4

it's increasing

Answer 5

Correct!

Now for lets do volume.
The units for volume is \[m^3\]
it can be any (length) to the power of 3

Volume goes from 0.85 m^3 to 1.27 m^3 to 1.7m^3
Is it increasing or decreasing?

Answer 6

The volume is also increasing

Answer 7

Yes, so if temperatures increases does volume increases or decreases?

Answer 8

As the temperature increases, the volume also increases.

Answer 9

Yes that is the relationship between volume and temperature.

Answer 10

For the second one,
You see that temperature increases by 50K each time right?
For volume 0.85m^3 to 1.27 m^3 to 1.7m^3 to 2.12m^3 to 2.54m^3
I would subtract it to see if there is a pattern.

1.27-0.85=0.42
1.7-1.27=0.43
2.12-1.7=0.42
2.54-2.12=0.42

So lets say the pattern is that every time temperature increases by 50K, the volume increases by 0.42m^3 as well.

Answer 11

1273.15K-400K=873.15K
But for every 50K, volume increases by 0.42m^3
So you divide
873.15K/50=?
The number you get from dividing; you would then multiply it by 0.42m^3 to get your answer.

Answer 12

okay thank you sooo much, now i can move on! :D

Answer 13

No problem!
Glad you understood
Thanks for being very responsive and cooperative.
