There are many differences between ideal gas and real gas; some of the main differences are as following:
- An ideal gas follows the formula PV=nRT but a real gas does not always follow this formula.
- There is no attraction between the molecules of an ideal gas. A real gas has significant particle attractions.
- The particles of an ideal gas lose no energy to its container. A real gas conducts and radiates heat, thereby losing energy.
- An ideal gas is infinitely compressible, a real gas will condense to a liquid at some pressure.
- Real gas particles have a volume and ideal gas particles do not.
- Real gas particles collide in-elastically (loses energy with collisions) and ideal gas particles collide elastically.
Time of decays approximately 2.853 days
<h3>Further explanation</h3>
Given
mass = 320mg iodine-131
No=320 mg
Nt=250 mg
t1/2 = 8 days
Required
t=time of decays
Solution
General formulas used in decay:

Input the value

Answer:
A
Explanation:
I would say A because the sun makes energy right so if you are looking for an arrow or arrows I would say A I hope this helps!! and have a great day or night
