Explanation:
The given data is as follows.
= 98.70 kPa = 98700 Pa,
T =
= (30 + 273) K = 303 K
height (h) = 30 mm = 0.03 m (as 1 m = 100 mm)
Density = 13.534 g/mL = 
= 13534 
The relation between pressure and atmospheric pressure is as follows.
P = 
Putting the given values into the above formula as follows.
P = 
= 
= 102683.05 Pa
= 102.68 kPa
thus, we can conclude that the pressure of the given methane gas is 102.68 kPa.
Where is the paragraph that we are summarizing v
Initial Conditions:
Volume=v1= 3.5 L
Temperature= T1 =298K
Final Conditions:
Temperature= T2= 285K
Volume= v2= ?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
Note:
Pressure is constant
so the equation become,
v1/T1 = v2/T2
3.5/298 = v2/285
v2 = 3.347 L
Answer:
Our sun is an averaged size star compare to other stars.. And the Iron are the heaviest element they can form.
