How does the Ideal gas law relate to hot air balloons?

It says that $Pprop1/V$...and thus it has NO FORMAL application to hot air ballooning...because pressure is formally constant. (Of course, as the balloon ascends, the atmospheric pressure DOES decrease...but to...

Good question! Let's look at the and the . Ideal Gas Law: PV=nRT Combined Gas Law: $P_1*V_1/T_1 = P_2*V_2/T_2$ The difference is the presence of "n" the number of...

The describes states that $(PV)/T=k$ is a constant for any fixed quantity of gas, but the extends this to say that the value of the constant is proportional to the...

According to , $color(red)(v prop1/p" "$when $" "color(green)(T" & "n$ constant. According to Charle's Law, $color(red)(v prop T" "$when $" "color(green)(p" "&" "n$ constant....

$"R=0.0821 L atm K"^(-1) "mol"^(-1)"$

...and while I have never done it since I lived in England, I still remember that the golden rule of scuba diving is NEVER HOLD YOUR BREATH....and a lot of...

Under certain conditions of temperature and pressure the ratio of the left and right sides of the ideal gas equation can be close to unity. One can then use...

You can fill 140 balloons. This is a disguised problem. We can use number of molecules of helium to calculate the number of moles. Then we can use the...

$"Charles' Law"$ states that a given quantity of gas has a volume directly proportional to the absolute temperature: $VpropT$, else $V=kT$. Solving for $k$, $V_1/T_1=V_2/T_2$, and $T_2=V_2/V_1xxT_1$ $T_2=(4.5xx10^2*L)/(1.89xx10^2*L)xx294*K$ $=$ $??K$

You are compressing a gas. Is the volume going to increase? Is it going to decrease? If you compress the volume of a gas what is going to happen to...
