Question

1. describe, on a particle level, what will happen to the density of the tungsten sample as its temperature is decreased.

if the temperature of the tungsten sample decreases, the particles will move slower and they will get closer together which makes the volume decrease and cause the density to increase.
mr fauvell has fallen on hard times and is trying to make a quick buck. he finds some old dirty oil from behind a restaurant and is trying to resell it as lemonade at a stand he built on the corner of flatbush and empire.

1. the oil is very thick and its particles are moving very slowly, so it is not pouring out of the pitcher well. what could mr. fauvell do to speed the particles up?

Explanation:

Step1: Recall particle - motion and temperature relation

The speed of particles is related to temperature. Higher temperature means faster - moving particles.

Step2: Determine the action to speed up particles

To speed up the particles of the thick oil, Mr. Fauvell should increase its temperature. This can be done by heating the oil.

Answer:

He could heat the oil.
