Ideal Gas Law Gas in a Piston Problem

AI Thread Summary
The problem involves a gas in a piston initially at 25 degrees Celsius and 4.0L volume, which expands when heated to 193 degrees Celsius. Using the Ideal Gas Law, the new volume is calculated after the pressure is increased to 4.3 atm. The equation P1V1/T1 = P2V2/T2 is applied, leading to a calculated volume of approximately 1.45L, rounded to 1.5L. The solution appears to be correct based on the calculations provided. This confirms the application of the Ideal Gas Law in determining the new volume under changing conditions.

Homework Statement


A gas is in a piston which is at 25 degrees celsius with a volume 4.0L is held in a room at atmospheric pressure. If the temperature is increased to 193 degrees celsius, the piston expands to it's maximum volume. If the pressure in the room is then increased to 4.3 atm, what is the new volume of the piston (temperature remains at 193 degrees celsius)?

T1 = 25 = 298.15K

V1 = 4.00L

P1 = 1.000atm

P2 = 4.3 atm

T2 = 466.15K

V2 = ?


Homework Equations



P1V1 / T1 = P2V2 / T2

The Attempt at a Solution



P1V1 / T1 = P2V2 / T2

V2 = P1V1T2 / T1P2

V2 = (1.000atm)(4.0L)(466.15K) / (298.15K)(4.3atm)

= 1.45L
= 1.5L

Just want someone to check my solution

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
