Metal conductivity generally goes down or resistivity goes up with temperature goes up.
Answer:
C
Explanation:
A - Crude oil is composed for hundreds of hydrocarbon, not less than ten.
B - Is formed in specific conditions of temperature and pressure
C - It's fractionated to form gasoline, lubricants, CH4, plastics and many other products made of hydrocarbon.
D - We have crude oil located more than 4000 yards below the surface in countries like Brazil
E - The crude oil is very thick and don't have an specific usage, so we need to refine it.
Answer:
P and V: inversely proportional
P and T: directly proportional
V and T: inversely proportional
Explanation:
For pressure and volume, as the volume goes up, meaning the container gets bigger, the pressure would go down. There would be more room in the container, so there would be less collisions between the molecules themselves and between the molecules and the container. This makes them inversely proportional.
For pressure and temperature, as the pressure goes up, there are more collisions, so the particles move faster. Temperature is the speed of the particles, so, since both pressure and temperature would go up at the same time, they are directly proportional.
For volume and temperature, this is similar to the PV relationship. As volume increases, there are less collisions between the particles. This means that the particles are going to move slower. Therefore, as volume goes up, temperature goes down, so they are inversely proportional.
Sorry this is super long, but I hope it fully explains the question for you! ☺
Im unsure :( maybe try looking up a calorie calculator
