PLEASE EXPLAIN AND YOU WILL GET BRAINLIST Ms. R is curious if the type of gasoline she uses in her car affects how many miles she can drive on a single tank of gas. (Fuel efficiency). Which of the following would be the BEST scientific question for her to test? 1) How does driving farther affect the type of gas used?

2) How does a Mazda compare to a Civic?

3) How does changing the type of fuel affect the number of miles a car can be driven on a single tank of gas?

4)How does the color of the car affect its internal temperature?

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
