# Another 'what am I' riddle (easy)! [closed]

I am colorless, odorless, tasteless, and invisible
When I am inside of you, you sound funny
But too much of me would kill you
And when I touch fire, it gets angry

What am I ?

• This seems really broad. From the number of answers already, there are a ton of colorless, odorless/tasteless gasses that change the pitch of your voice, are dangerous in large quantities, and react with fire... Perhaps you could add some other clues (Maybe something about its chemical formula) to narrow down the possible answers? – DqwertyC Oct 27 '17 at 16:33

I'm going to say

Helium (gas)

I am colorless, odorless, tasteless, invisible

Yeah, those seem to match up, although Helium from a store tank usually has a bit of a scent to it.

When I am inside of you, you sound funny

Your voice gets higher when you inhale Helium

But too much of me would kill you

Over-inhalation of Helium frequently knocks people out, and too much Helium without fresh air would indeed kill you

And when I touch fire, it gets angry

This is a bit more of a stretch, but since Helium isn't flammable, perhaps fire gets angry because it can't burn it up, and burning things is pretty much all fire wants to do.

It's

Hydrogen gas $\text{H}_2$

I am colorless, odorless, tasteless, invisible

Just like most gases

When I am inside of you, you sound funny

Also like Helium

But too much of me would kill you

Well, if there's no oxygen anymore, you die.

And when I touch fire, it gets angry

$\text{H}_2$ burns like hell.

Oxygen

I am colorless, odorless, tasteless, and invisible

Well, it is, unless someone "cut the cheese" (but that's not oxygen anyway)

When I am inside of you, you sound funny

The arteries transport oxygen.

But too much of me would kill you

And when I touch fire, it gets angry

Oxygen makes the fire burn.

• How does it make you sound funny? – Octopus Oct 27 '17 at 20:36

It is

Nitrogen (N)

As,

Nitrogen is colorless, odorless, tasteless, and invisible

When I am inside of you, you sound funny

Nitrous oxide (laughing gas, as it is usually called), when inhaled makes us laugh OR it can be cracking of knuckles / body joints which is due to Nitrogen / its compound in gaseous form. It is poisonous in large quantities, when inhaled

And when I touch fire, it gets angry

It does not support a fire rather it tries to explode / form an explosive environment.

you are

Methane

I am colorless, odorless, tasteless, and invisible

methane in its natural state is odorless colorless and tasteless

When I am inside of you, you sound funny

tummy rumble!

But too much of me would kill you

And when I touch fire, it gets angry

methane is a natural gas used for burning!

Its

Nitrous oxide (N2O)

I am colorless, odorless, tasteless, and invisible

At room temperature it is colourless, invisible ,odourless and tasteless(with a very slight sweet taste that is negligible)

When I am inside of you, you sound funny

Its also name as "laughing gas" due to the euphoric effects upon inhaling it.

But too much of me would kill you

Nitrous oxide is used as anaesthetic but overdose blocks blood vessels and can kill a person.

And when I touch fire, it gets angry

Though it is non-flammable at room temperature but when mixed with a flammable material it gets very dangerous by providing more oxygen than air alone, hence a more powerful combustion.

It really could be almost anything, so I'll guess

Sulphur Hexaflouride

I am colorless, odorless, tasteless, and invisible

It is all of these

When I am inside of you, you sound funny

It's heavier than oxygen so it makes your voice sound super deep

But too much of me would kill you

Like helium it can make you suffocate if you inhale too much.

And when I touch fire, it gets angry

Creates toxic fumes when introduced with fire

• Sulphur compounds having no odour is rare – Mea Culpa Nay Oct 28 '17 at 2:59
