The equation for Charle's Law

A. $$\frac{{{V_2}}}{{{V_1}}} = \frac{{{T_2}}}{{{T_1}}} = \frac{{273 + {C_2}}}{{273 + {C_1}}} = {\text{Constant}}$$

B. $$\frac{{RA}}{{RB}} = \sqrt {\frac{{DB}}{{DA}}} $$

C. $$\frac{{{P_1}{V_1}}}{{{T_1}}} = \frac{{{P_2}{V_2}}}{{{T_2}}} = {\text{Constant}}$$

D. $$\frac{{0.4645B}}{{273 + t}}$$
