A gas isn’t heated from 298 k to 367 k while it’s volume changes from 2.5 L to 3.9 L. If the initial pressure of the gass is 1.1 atm , what is the final pressure of the gass

Answers

Answer 1
Answer:

Answer:

0.8684 atm

Explanation:

Using combined gas equation,

PV / T = k

P1*V1 / T1 = P2*V2 / T2

P1 = 1.10 atm

P2 = ?

V1 = 2.5L

V2 = 3.9L

T1 = 298k

T2 = 367k

P1*V1 / T1 = P2*V2 / T2

Making P2 the subject of formula;

P2 = P1*V1*T2 / V2*T1

P2 = 1.1*2.5*367 / 3.9*298

P2 = 1009.25 / 1162.2

P2 = 0.8684 atm
Answer 2
Answer:

Here you go

This problem can be solved using one of the different gas laws, which is shown below:


PV/T


Given:


P1 = 1.1 atm

V1 = 2.5 L

T1 = 298 K


P2 = ?

V2 = 3.9 L

T2 = 367 K


Substituting the given:


P1V1/T1 = P2V2/T2


(1.1 * 2.5)/298 = (P2 * 3.9)/367

P2 = 0.868 atm

Please help me with this. Finding speed.

Answers


What you need is a definition of average speed.  Here it is:

     Average speed = (distance covered) / (time to cover the distance) .

For the race car in the question:

            Average speed = (200 mile) / (2.5 hour)

                                     = (200 / 2.5)  (mile/hour)

                                     =        80  miles per hour .

That doesn't seem all that fast for a race-car.
But the math is bullet-proof.     
the speed is 80 m/h you find it by dividing the distance by time

All of the following help to reduce the problem of social traps except ___________. Please select the best answer from the choices provided modelilng altruistic behaviors educating individuals about the effects of social traps establishing laws that decrease cooperative behavior establishing regulations on behaviors that have collective effectsIT WAS C

Answers

Answer:

Establishing laws that decrease cooperative behaviour.

Explanation:

A social trap refers to short term benefits, but long terms loss in a certain social group, that's why is called trap. One good example of social trap could be overexploitation of resources. Our societies is inside this social trap, which help to develop the economy, but with a long term ecology costs, because it degrades complete ecosystems.

So, in this case, the only answer that don't contribute to reduce this social problem, it's "establishing laws that decrease cooperative behaviour", because the lack of cooperativeness is one way to ensure the perpetuation and development of social traps.

All other options, actually contributes to reduce this social phenomenon. Modelling altruistic behaviours, education, and regulations on behaviour which could impact collectives, all of these are positive decisions that improve our social intelligence, and could ensure the reduce of social traps.

Explain why the moon can be seen from earth

Answers

The moon has an orbit around the earth and we can see it at night because of the reflection of the sun's rays and energy that bounce back to the earth. This is what gives the moon the brilliant white glow. It's important to also remember that the earth has a rotation and an orbit around the sun.

The moon can be seen from Earth because the sun's rays hit the moon, causing the light to be reflected by the moon.


In shorter words:


When the sun's rays hit the moon, the light reflects on the moon.
