Question

Please help: Medal will be given. The volume of gas varies directly with temperature and inversely with pressure. Volume is 100 m3 when temperature is 1508 degrees and pressure is 15 lb/cm2. What is the volume when the temperature is 2508 degrees and the pressure is 20 lb/cm2?

Answer 1

\[\frac{p_1 \times v_1}{T_1}=\frac{p_2 \times v_2}{T_2}\]

Answer 2

where p1 is the pressure and v1 is the volume at T1 =1508 degrees

Answer 3

can you just tell me if my answer is right 147.73m^3

Answer 4

do you agree with the formula? have you done such a thing?

Answer 5

its not letting me see your formula for some reason.. but i know v=kt/p

Answer 6

\[\frac{100 \times 15}{1508}=\frac{20 \times v_2}{2508}\]

Answer 7

100=k*1508/15
k=1500/1508
v= (1500/1508)*2508/20
=147.73m^3

Answer 8

(p1x v1)/T1=(p2xv2)/T2

Answer 9

can you see this formula now?

Answer 10

yes your answer is correct

Answer 11

yes!

Answer 12

it is similar to my short cut concluded formula based on the definition of your question...

Answer 13

you went and found the constant of proportionality then repeated the steps, i just made the whole thing in one steps, so they are the same, all roads lead to Rome...

Answer 14

oh I see what your saying! so your saying your step is just easier then what i did? and my answer and steps are correct though?

Answer 15

exactly...

Answer 16

well i did not mean it is easier as much as i meant they are different ways to solve the same problem...

Answer 17

okay I totally see what you are saying!! and my answer is correct right?

Answer 18

yes if and only if you did not make an error with the calculator...

Answer 19

is that what you got as an answer?

Answer 20

so now you are more confident to recheck your answer again using the calculator...

Answer 21

yes i can see the answer is logical from the figures...

Answer 22

okay thank you for your help!!!

Answer 23

well i am getting from computer calculator 124.73
