The correct answer is I disagree. Elements form all pure substances, but some pure substances include elements bonded together to form molecules and compounds.

Elements are pure substances but these elements also make other things such as water. The water molecule is made of two elements called oxygen and Hydrogen. Now water itself is a pure substance as it is chemically bonded hydrogen and Oxygen but it is composed of more than one element

I don't understand why when you use a straw the higher pressure outside of it pushes the water up the straw.
ValentinkaMS [17]
When material stuff is free to move, it moves away from stronger force on it to weaker force on it. OK ? Now take it to the next step: When material stuff is free to flow ... like liquid or gas ... it flows from higher pressure to lower pressure. That's what makes wind, and that's why water comes out of a garden hose when you open the nozzle. It doesn't amaze you at all when you INCREASE the pressure at one end of the straw (blow into it), and air moves DOWN and out of it. So it shouldn't bother you that when you DECREASE the pressure at your end, anything that's free to flow UP the straw will do that.

Why should mass not be represented by an arrow?
34kurt
Arrows represent vector quantities, which have both a magnitude (size) and a direction. For example on Earth, weight acts towards the planet's centre due to the effect of the gravitational field, and has a magnitude in Newtons (e.g. 10N). However, mass is a scalar quantity, meaning that it only has a magnitude - it's just the amount of stuff you have. It would be like an arrow without a direction, which of course is not possible (at least not in this universe...)

If an object has a mass of 38 kg, what is its approximate weight on earth?
klasskru [66]
38*10=380 N
To be more exact, 38 should be multiplied by 9.8 instead of 10.
