Answer:

A graph is plotted between logV(lit) on y-axis and logT(K) on x-axis at a constant pressure of 0.0821 atm, for 2 moles of gas. Find the ratio between V and T? (A) 2 (B)4 (C)6 (D)7

Explanation:

I don't know

Answer 2

Concept:

Ideal gas law is additionally called the overall gas equation is that the equation of state of a hypothetical or perfect gas. it's a decent approximation of the behaviour of the many gases under certain conditions.

Given:

We are given a graph is plotted between $\log V$ on $y-$ axis and $\log T$ on $x-$axis.

Find

We have to search out the ratio between $V$ and $T$.

Solution

Ideal gas equation could be a combination of Boyles’s law, Charles’ law, Avogadro’s law and Gay-Lussac’s law. the best gas law is written as:$PV=nRT$; where $P,V,T$ and nare pressure, volume, moles and temperature.

Here, $P$ and $n$ are given as $0.0821$ atm and $2$mol. aside from pressure, $R$ and $n$, other quantities are variable. The graph has to be plotted in between the variable quantities only.

First put the values given the ideal gas equation, $0.0821\timesV=2\times0.0821\times T$; the term$0.0821$ is canceled with one another, the equation is now,$V=2T$.

Now, divide both sides by $T,$ we get

$\begin{aligned}\frac{V}{T}&=\frac{2T}{T}\\ \frac{V}{T}&=2\end$

Thus, the ratio between $V$ and $T$  is $2.$

Hence, option (A) is correct.
