What is the entropy change associated with the expansion of one mole of an ideal gas from an initial volume of v to a final volume of 5.50v at constant temperature?

Entropy is 14.17 J/k

Explanation:

The entropy change associated with the expansion of gas from v to 5.5v is given by

S=Rin(Vf/Vi)

We're Vi= iniatial volume and Vf is final volume

Hence S= 8.314in(5.5v/v)

S=14.17J/K

the answer is b ) square root of 5

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
