The temperature : 263.016 K
<h3>Further explanation</h3>
Combined with Boyle's law and Gay Lussac's law
P1 = initial gas pressure (N/m² or Pa)
V1 = initial gas volume (m³)
P2 = gas end pressure
V2 = the final volume of gas
T1 = initial gas temperature (K)
T2 = gas end temperature
P1=760 mmHg
V1= 4 L
T1 = 275 K
P2=704 mmHg
V1=4.13 L

D

The first image shown at the left hand side is a pi bond. The other two images show sigma bonds.
In chemistry, a bond results from the overlap of atomic orbitals. This overlap may be end to end (sigma bond) or side by side (pi bond). Having said this, it is easier to decide whether the bonds in the image shown are sigma or bi bonds.
If we label the images; 1,2,3 from left to right, we can see that the overlap in image 1 is side by side. The electron density lies above and below the plane of the bond. This is a pi bond. In images 2 and 3, the overlap occurs in an end to end manner. This is a sigma bond.

Option B: Strength of chemical bonds
Hardness defines the strength, it can not be compared with surface roughness as a smooth surface can be harder or difficult to break than a rough surface. The mass and weight of a substance matters while comparing density of substance or how heavy it is but it is not directly proportional to the hardness of the substance. Thus, equal masses of two substance can not be considered equally hard. Hardness depends on the inter-molecular interaction or forces within a substance, if the inter-molecular interactions are strong or the strength of chemical bonds is strong then the substance is more hard.
Therefore, hardness is directly proportional to strength of the chemical bonds.
