Experts are tested by Chegg as specialists in their subject area. What is the relationship between the number of moles and pressure? With temperature set at 100 K, press Record. If two variables are directly proportional , an increase in the independent variable will cause the dependent variable to increase at the same rate. the amount of moles decreases the pressure 7. V1/T1=V2/T2 (pressure and number of moles constant) (as v doubles t doubles) (when v is zero t is zero), directly proportional, (Suppose the temperature is increased. Explanation: Doubling the temperature would double the volume while halving the number of moles would decrease the volume by half, so the changes produced by these two variables cancel each other out. P1V1/T1 = P2V2/T2, so P1V1T2/P2T1 = V2 = P1/P2 x T2/T1 x V1 P1/P2 = 2; (P2 = 0.5P1) T2/T1 =2 so 2*2 = 4 and V2 = 4V1 A. 2013-03-08 17:14:41. . If we keep the pressure constant, temperature is doubled or if temperature is constant pressure is doubled since the volume is kept constant. Doubling the speed will increase kinetic energy by a factor 22 = 4. The device that measures atmospheric pressure is called a barometer. Pressure and Temperature have a direct relationship as determined by Gay-Lussac Law P_1/T_1 = P_2/T_2 Pressure and temperature will both increase or decrease simultaneously as long as the volume is held constant.
