Ashort, thick, cold wire is the best conductor. a shorter wire will allow electricity to move through at a higher rate than a longer wire. how well a material conducts current is an internal factor affecting resistance. if you double the length of a wire, you cut the resistance in half. if you double the thickness of a wire, you cut the resistance in half. superconductors have no measurable resistance. the higher the temperature of the conductor, the lower the resistance. the resistance in a wire with less thickness is less. thickness, length, and temperature are internal factors that affect resistance. when a light is first switched on, the light bulb's filament has a lower resistance than after it gives off light for awhile. true false

While studying chemical reactions and conservation of matter, sarah's class conducted a variety of experiments. sarah and her lab partner found the mass of a wax candle and placed the candle in a flask. the students lit the candle and let it burn to completion. all that was left was wax and charred candle wick. per their teacher's instructions, the students found the mass of the products. their data can be seen in the data table. formulate a hypothesis the students could test to explain why the experiment did not support the law of conservation of matter. a) the students could repeat the experiment using different candles; there might have been a flaw in the candle. b) the experiment should be repeatable. the students should run several trials and then take an average of the after mass in each trial. c) the students should have someone in the class check their measurement skills as they repeat the experiment. they may have made an error using the balance. d) the students should burn the candle in a container that has some type of lid so that any gas that is a product of the reaction can be contained and massed. submit
