Question

what is the formula charles’ law?
t₁ = v₂ / t₂
vt = vt
t₁ / v₁ = t₂ / v₂

Explanation:

Charles' Law states that for a fixed amount of gas at constant pressure, the volume (V) is directly proportional to the absolute temperature (T). The correct formula is derived from the proportionality \( V \propto T \), leading to \( \frac{V_1}{T_1}=\frac{V_2}{T_2} \) (or rearranged as \( \frac{T_1}{V_1}=\frac{T_2}{V_2} \) when considering the inverse proportion of temperature and volume in some contexts, but the standard form is \( \frac{V_1}{T_1}=\frac{V_2}{T_2} \); however, among the options, \( \frac{T_1}{V_1}=\frac{T_2}{V_2} \) is the closest correct representation of the proportionality relationship). The first option is incorrect as it does not follow the law, and the second option \( VT = VT \) is a trivial and incorrect representation.

Answer:

The option with \( \boldsymbol{\frac{T_1}{V_1}=\frac{T_2}{V_2}} \) (the third option from the left)
