Question

ricardo finds an online site about the gas laws. the site shows the equation below for charless law.

( v _ { 1 } t _ { 1 } = v _ { 2 } t _ { 2 } )

what change would correct the error on the site?

\charless law\ should read \gay - lussacs law,\ which explains changes in volume and temperature.

the symbol for ( t _ { 2 } ) should be smaller than for ( t _ { 1 } ) because if volume increases, then temperature should decrease.

each ( t ) should be replaced by a ( p ) in the equation because charless law describes changes in volume and pressure.

the volume should be divided by temperature on each side of the equation.

Explanation:

Charles's law states that \(V\propto T\) (at constant pressure), so the correct equation is \(\frac{V_1}{T_1}=\frac{V_2}{T_2}\). The given equation \(V_1T_1 = V_2T_2\) is wrong. Dividing volume by temperature on each side would correct it. Gay - Lussac's law is about \(P\) and \(T\) (\(P\propto T\) at constant volume). In Charles's law, \(V\) and \(T\) are directly proportional (if \(V\) increases, \(T\) increases). Charles's law is about \(V\) and \(T\), not \(V\) and \(P\).

Answer:

The volume should be divided by temperature on each side of the equation.
