Option D. maintain their positions.
Pressure does not modify the relative position of the atoms in solid matter. The atoms are kept in position by the atomic and molecular bonds whose length is a feature of every pair of atoms.
For example, all the bonds of C-C and C-H in the wood will have the same bond length
Explanation:
The given data is as follows.
n = 2 mol, P = 1 atm, T = 300 K
Q = +34166 J, W= -1216 J (work done against surrounding)
=
Relation between internal energy, work and heat is as follows.
Change in internal energy (
) = Q + W
= [34166 + (-1216)] J
= 32950 J
Also, 
=
32950 J = 

1321.06 K + 300 K =
= 1621.06 K
Thus, we can conclude that the final temperature of the gas is 1621.06 K.
Answer:
carbon dioxide is added to the atmosphere naturally when organisms respire or decompose,
Explanation:
Answer:
Given
mass of solute (m) =20.5g
mass of solvent( ms) =155g
solution
malality =mX1000/mrxms
M=20.5x1000/62x155
M=2.1332
