Answer:
Assuming pressure is held constant,the question reduces to a ratio and proportion type of question where;
At constant pressure,
21.0ft³-55.0°F
11.0fy³=11.0ft³/21.0ft³×55°F
The temperature is 28.809°F≈29°F
The property makes the materials used in fiber optic cables is:
C. High density
<h3>Fiber optic cables:</h3>
They transfer data signals in the form of light and travel hundreds of miles significantly faster than those used in traditional electrical cables. Fiber is immune to electrical interference. There is no cross - talk between signals in different cables and no pickup of environmental noise. Information traveling inside the optical fiber is even immune to electromagnetic pulses generated by nuclear devices.
Thus, correct option is C.

Crystal field splitting is the difference in energy between d orbitals of ligands. Crystal field splitting number is denoted by the capital Greek letter Δ. Crystal field splitting explains the difference in color between two similar metal-ligand complexes.
<h3>What is crystal field splitting of d-orbitals?</h3>
The splitting of fivefold degenerate d orbitals of the metal ion into two levels in a tetrahedral crystal field is the representation of two sets of orbitals as Td. The electrons in dx2-y2 and dz2 orbitals are less repelled by the ligands than the electrons present in dxy, dyz, and dxz orbitals.
<h3>Which of the following factors affect crystal field splitting energy?</h3>
There are the following factors that affect the crystal field splitting. These are the nature of ligands, coordination number, arrangement of ligand, size of a metal atom, charge on the metal atom, size of ligands, electronegativity, and interatomic distance.

The kinetic energy of gas particles depends on temperature. Greater the temperature higher will be the average kinetic energy
Kinetic energy is related to the temperature as:
KE = 3/2 kT
where k = Boltzmann constant
T = temperature
In the given example, since the temperature of O2 gas is maintained at room temperature, the average KE will also remain constant.
The fifth postulate of the kinetic molecular theory which states that the temperature of the gas depends on the average KE of the particles of the gas explains the above observation.
Let us say the molar mass of solute =24g.
mole of the solute = 0.8g x (1mol / 24g)
= 0.0333mol
molality = mol of solute / kg of solvent
= 0.333mol / 0.50kg
= 0.666M or 0.67M
