Name an example of a hydrocarbon that you rely on. Is it a gas, liquid, or solid at room temperature? And Why?

I have a propane grill. a gas at room temp and pressure -- but is sold in tanks at higher pressure so it is a liquid. === Why? low molec. mass and low intermolecular attraction forces so the molecules do not attract and form a liquid.

most humans rely on sugars and starches for energy.
They are solids at room temperature.
There is no why

Let's see. I don't own a car or any other internal combustion engine. My kitchen is all electric. My electric utility gets its energy from hydropower and geothermal sources. So I suppose I rely on the trucks that deliver food to my grocery, and most of them are fueled by diesel, which is a liquid. Diesel is a liquid at room temperature for the same reason water flows downhill -- because that's the way things are.
[Although it can be argued that diesel is not strictly a hydrocarbon.]
Wait -- I do use cigarette lighters which contain butane, which is certainly a hydrocarbon. (Although I hesitate to say I rely on it. Matches would work just as well.) Butane is a gas at room temperature and atmospheric pressure. (Although it is a liquid when pressurized inside the lighter.) The reason is that butane's boiling point at atmospheric pressure is -1°C, which is below room temperature. And in general it is a gas because it has a relatively low molecular weight.
