Question

what is the formula for boyles law?
$p_1/v_1=p_2/v_2$
$p_1v_2=p_2v_1$
$p_1v_1/p_2v_2$
$p_1$

Explanation:

Boyle's Law states that for a fixed amount of gas at constant temperature, the pressure and volume are inversely proportional, and the product of pressure and volume remains constant. So the formula is \( P_1V_1 = P_2V_2 \), which can be rearranged to \( P_1V_2 = P_2V_1 \) (by cross - multiplying \( P_1V_1 = P_2V_2 \)). The first option \( \frac{P_1}{V_1}=\frac{P_2}{V_2} \) would imply a direct proportionality between pressure and volume, which is incorrect. The third option \( \frac{P_1V_1}{P_2V_2} \) is not a valid formula for Boyle's Law.

Answer:

B. \( P_1V_2 = P_2V_1 \) (assuming the second option is labeled B, as it's the one with the red hand icon indicating the correct choice in the visual)
