Which of these statements describes this mathematical equation? a) the final pressure of a gas is directly proportional to volume and temperature change. b) the final pressure of a gas is directly proportional to volume change and inversely proportional to temperature change. c) the final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature change. d) none of the above.

The correct answer is C. The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature change.

Explanation:

The combination of the laws of Charles, Boyle and Gay-Lussac provides the combined gas law, which takes the same functional form as the ideal gas law, except that the number of moles is not specified, and the ratio of PV to T simply taken as a constant.

This equation tells us that the pressure of a gas is inversely proportional to the volume of the gas and is directly proportional to its temperature.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
