The answer to the question is b
C. alpha = nucleus of a helium atom
beta = electron
gamma = photon
Answer: 0.185 L
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 0.98 atm
= final pressure of gas = 1 atm (at STP)
= initial volume of gas = 0.165 L
= final volume of gas = ?
= initial temperature of gas = 
= final temperature of gas =
(at STP)
Now put all the given values in the above equation, we get:


Thus the volume of this gas at STP be 0.185 L
This answer is B. Peer pressure
48 square unit
Explanation:
Given parameters:
Surface area of sphere = 4πr²
value of π = 3
radius of sphere = 2
Unknown:
Surface area of sphere = ?
Solution:
To solve we input the given parameters in the formula for the surface area of the sphere.
S. A = 4πr²
r is the radius of the sphere
π is a constant whose value is 3
S.A = 4 x 3 x 2² = 48 square unit
