Answer: Option (B) is the correct answer.
Explanation:
Radiation involves transfer of energy or heat with the help of electromagnetic waves.
For example, radiations from Sun help in transfer of energy or heating of object on which it falls. Like, when radiations are falling on a metal rod then after sometime the rod becomes hot due to absorption of radiations from the Sun.
Thus, we can conclude that Sunlight travels through space without the aid of fluids or solids describes how heat is transferred by radiation
Answer:
The term Decimal is coined from the word Decimus. Decimus is a Latin word which means ‘tenth’.
The Decimal system is a system of numbering that is based on multiples of tens. It is flexible and easy to convert from one metric to another.
The preference of the term over the Metric System is because the word Metric is related more to the measurement of lengths if we looked at the origin of the word which is French.

Answer:) is related to the change in free energy of the reaction--d
Explanation:
For any reaction that is taking place at any moment the change in Gibbs Free Energy is related to the reaction quotient as
ΔG=ΔG⁰+RTlnQ
where R-Universal Gas Constant, T- Temperature in Kelvin, Q is the reaction quotient
Now when the system is in equilibrum, ΔG⁰ which is the standard Gibb's Free Energy,is then defined as
ΔG⁰=−RTlnK ,
where K is the equilibrium constant. because ΔG becomes 0 and reaction quotient Q = K
The equilibrum constant is related to the change in free energy of the reaction.
because when ΔG is negative, the value of K is high which leads to a spontaneous. reaction
when ΔG is positive, the value of K is low, which leads to a spontaneous. reaction in the opposite direction.
