Which one of these is a liquid? AND THERE IS AN ANSWER!! PLEASE HELP!!! :(?

Question

Which one of these is a liquid?
ice, gold, helium, or iron

Answer 1

That's not a complete question because you have to specify the temperature or pressure also, otherwise, the answer can vary.
If you are talking about the state of the material at room temperature, then, given enough time, ice can melt to give water because its melting point is at zero degree C even though it is in solid form. Both iron and gold are in solid state (because their melting points are way above room temperature), while helium is in gas form (because its melting point is much much lower than room temperature).
However, given enough heat, you can melt both iron and gold.
On the other hand, if you increase the pressure or reduce the temperature enough, helium can condense back to liquid too.

Answer 2

At the right temperature, each is a liquid. In order of temp, high to low, iron, gold, ice, and helium all become liquids.

Answer 3

Like others said, it depends on the temperature, as any of them can be a liquid at some point. However, if the question is just referring to the substance at standard room temperature, 20*C, the answer would be ice.

Answer 4

actually all of them can be liquid.
phase of a material (gas, liquid, solid) depends on their temperatur and/or pressure.
example : ice can melt into water

gold and iron can be melt if given enough heat.
we have to heat and melt them first before we cast it into some form.

and gas (helium, nitrogen) can become liquid if they are compressed.

Answer 5

All of these can be in liquid form at the right temperature and pressure.

Answer 6

ice

Answer 7

ice

Answer 8

any can be a liquid
