C.
14 cm
D.
16 cm
The perimeter of a square is calculated using the formula P = 4s, where P is the perimeter and s is the length of one side. Given that the perimeter is 48 cm, we can set up the equation: 4s = 48. Dividing both sides by 4 gives us s = 12 cm. Therefore, the length of one side of the square is 12 cm, which corresponds to option B.

Boyle's Law states that the pressure of a given mass of gas is inversely proportional to its volume when the temperature is held constant. This means that as the volume decreases, the pressure increases, and vice versa. This relationship is crucial in understanding gas behavior in various scientific and industrial applications. Charles's Law relates volume and temperature, Avogadro's Law deals with the volume of gas and the number of moles, while Gay-Lussac's Law involves pressure and temperature.
