Answer:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
4.42 g mass of CCl4 is required to prepare a 0.25 m solution using 115 g of hexane.
It's easy to find the molecular mass of a compound with these steps: Determine the molecular formula of the molecule. Use the periodic table to determine the atomic mass of each element in the molecule. Multiply each element's atomic mass by the number of atoms of that element in the molecule.
The molar mass of any compound can be found out by adding the relative atomic masses of each element present in that particular compound.
Hexane is an organic compound, a straight-chain alkane with six carbon atoms and has the molecular formula C₆H₁₄.
Therefore,
⇒ 0.115 g of Hexane x (0.25 mol CCl4/1 mol hexane) x (153.81 g of CCl4/1 mol CCl4) = 4.42g CCl4.

Explanation:
The substance A and B will mix into one solution as it is a solvent interactions which is greater than or equal to the solute- solute and the solvent-solvent interactions. Thus when such interactions occurs, it is greater or equal to the some of the other two possible interactions. And here both have the same kind of interaction, and same magnitude, so they will makes to form a solution and mixes properly and spontaneously.
Answer:
B. The transition of heat across matter
