Answer: Option (c) is the correct answer.
Explanation:
Entropy is defined as the degree of randomness. This means that more is the number of collisions taking place between atoms of a substance more will be the randomness.
Therefore, more will be the entropy of substance. We cannot measure the entropy but we can measure the change in entropy of a substance.
A thermometer is a glass tube that contains a liquid column generally mercury, and it is usually used to measure the temperature of human body.
A calorimeter is a device or apparatus that is used in a chemical reaction to measure the amount of heat involved.
Therefore, we can conclude that the student can't measure entropy directly, only an entropy change.

The important point is that the surface area<span> to the </span>volume ratio<span> gets smaller as the </span>cell<span> gets larger. Thus, if the </span>cellgrows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate theincreased cellular volume<span>.

Answer:
= 1.806 × 10^25 molecules.
Explanation:
1 mole of CO2 contains 6.02 × 10^23 molecules
30 moles of CO2 will contain ( 30 × 6.02 × 10^23 )
= 1.806 × 10^25 molecules.
