9-34: To determine if the octane level of a gasoline influenced gas mileage, ten cars were driven over a 100-mile road test first using a 87-octane gas and then a 93-octane gas. The miles/gallon measured for the ten cars were 87-octane: 17.6, 19.1, 18.3, 18.8, 19.5, 19.0, 18.1, 17.9, 19.2, 18.4 93-octane: 19.8, 19.2, 19.4, 18.9, 19.1, 20.0, 19.9, 20.3, 18.4, 18.6 Does increasing the octane increase the mileage

h let me think

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

i don,t know so just answer mine
