This equation is known as the ideal gas law, and it can be used to predict the behavior of many gases at relatively low pressure. from this equation, you can see that as the temperature of a gas increases, a) the pressure of the gas increases. b) the number of moles of gas will go down. c) either the pressure of the gas, the volume of the gas, or both, will increase. d) either the pressure of the gas, the volume of the gas, or both, will decrease.

Two loudspeakers, 5.5 m apart and facing each other, play identical sounds of the same frequency. you stand halfway between them, where there is a maximum of sound intensity. moving from this point toward one of the speakers, you encounter a minimum of sound intensity when you have moved 0.33 m . assume the speed of sound is 340 m/s.part a) what is the frequency of the sound? part b) if the frequency is then increased while you remain 0.21 m from the center, what is the first frequency for which that location will be a maximum of sound intensity? express your answer to two significant figures and include the appropriate units.
