Answer:
5 atm
Explanation:
Gay-Lussac's Law states that pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature.
P1 / T1 = P2 / T2
Plug the information given in and you get
(10atm)(10 K)=(P2)(20K)
Divide both sides by 20 K and you get the unknown pressure which is 5 atm.
Explanation:
(a) Formula for critical stress is as follows.
![\sigma_{c} = \frac{k_{IC}}{\tau \sqrt{\pi \times a}}](https://tex.z-dn.net/?f=%5Csigma_%7Bc%7D%20%3D%20%5Cfrac%7Bk_%7BIC%7D%7D%7B%5Ctau%20%5Csqrt%7B%5Cpi%20%5Ctimes%20a%7D%7D)
Here,
= 54.8
= 0.99
a = 0.8 mm =
m
Putting the given values into the above formula as follows.
![\sigma_{c} = \frac{k_{IC}}{\tau \sqrt{\pi \times a}}](https://tex.z-dn.net/?f=%5Csigma_%7Bc%7D%20%3D%20%5Cfrac%7Bk_%7BIC%7D%7D%7B%5Ctau%20%5Csqrt%7B%5Cpi%20%5Ctimes%20a%7D%7D)
= ![\frac{54.8}{0.99 \times \sqrt{3.14 \times 0.8 \times 10^{-3}}}](https://tex.z-dn.net/?f=%5Cfrac%7B54.8%7D%7B0.99%20%5Ctimes%20%5Csqrt%7B3.14%20%5Ctimes%200.8%20%5Ctimes%2010%5E%7B-3%7D%7D%7D)
= 1107 MPa
Hence, value of critical stress is 1107 MPa.
(b) Applied stress value is given as 1205 MPa and since it is more than the critical stress (1107 MPa) as a result, a fracture will occur.
Answer:
The answer is glucose (C6H12O6)
Answer:
The answer to your question is 4.14 g of O₃
Explanation:
Data
mass of nitrogen dioxide = 3.97 g
mass of ozone = x g
Reaction
NO₂ (g) + O₂ (g) ⇒ NO (g) + O₃ (g)
- Check that that reaction is balanced
Reactants Elements Products
1 N 1
4 O 4
This reaction is balanced
- Calculate the molecular mass of NO₂ and O₃
NO₂ = 14 + 32 = 46 g
O₃ = 48 g
- Calculate the mass of Ozone formed.
46 g of NO₂ ------------------ 48 g of O₃
3.97 gof NO₂ ---------------- x
x = (3.97 x 48 ) / 46
x = 190.56 / 46
x = 4.14 g of O₃
When it is filled with Helium it will expand and become more dense in the hot car. But when it becomes dense the gas molecules fly around in different directions, they collide with other objects and create pressure which can cause the balloon to pop.
