Find the total change in the internal energy of a gas that is subjected to the following two-step process. in the first step the gas is made to go through isochoric heating until 5460 j of heat is transferred into the gas and its pressure is 3.72 ✕ 105 pa. in the second step it is subjected to isobaric compression until its volume decreases by 7.50 ✕ 10−3 m3 and 1220 j of heat is transferred out of the gas. what is the total change in internal energy of this j?

Explanation:

We need to divide the entire process into two different sections, as well

For process 1 we define the following,

It is an Isochoric heating process,

Where

On the other hand for process 2

It is an Isobaric compression process,

Where

Thus,

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.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
