Thicker wires offer less resistance.  Jill had two wires in her lab, one was twice the thickness of the other and she measured the resistance of each. She saw that the thicker or thinner one showed less resistance?
thicker

The surface is heated by the Sun and some of that heat radiates back into the air. This makes the temperature higher near the surface than at higher altitudes.  Paul started at the base of a mountain and climbed to its peak. The sky was clear and the sun was beating down on him all day. However, he noticed there was a clear temperature difference between the surface's temperature and the temperature at the top of the mountain peak. Where would he feel more heat Surface or Mountain Peak?
Surface

As you increase the number of carbon atoms in a hydrocarbon, the number of isomers quickly increases.  Jeffrey decreases the number of carbon atoms to a natural gas hydrocarbon in a lab. The isomers increase or decrease?
decrease

Longer length resistors will offer more resistance than shorter resistors.  Olivia has a miniature resistor and a normal sized one. Which resistor offers more resistance the miniature resistor or the normal resistor?
the normal resistor
