it's like you know ,Gold or any other substance cannot be called "solid,liquid or gas" because we can change the state by simple increasing or decreasing the temperature.

Because the standard 'state' (plasma,gas,liquid,solid, bose-einstein condensate, what-have-you) of a given material is generally taken to be the material's state at about 300K (roomish temperature) and 1 standard atmosphere.
Under those conditions, mercury is liquid.
If you're going for clarity, say that mercury is a liquid at standard temperature and pressure.

I think you forgot or didn't pay attention to why mercury is said to be a liquid in the first place, i.e. when it's at the STP(Standard Temperature and Pressure) or just room temperature.
Say, look at nitrogen. It's gas when in room temperature. But if you decrease the gas's temperature enough in some container, it can be turned into liquid. Thus, the very familiar term---liquid nitrogen.
I think mercury can be turned solid under a very low temperature. Not sure how low though.

Well, that is the property of that substance.We describe it as a liquid because that is (liquid) the form when it is in a room temperature.Remember, water it is a liquid but on the other hand it can also be a solid. By subjecting it into a high/low temperature, its characteristics can be change,like solid-liquid-gas.

Usually, a substance is called a gas, liquid or solid based on its state at room temperature. At room temperature, mercury is a liquid.

We say a material liquid, solid or gas by what state its stable form is. Mercury as a liquid is stable and it pocessess liquid properties such as surface tension, viscosity etc. More over when cooled it transforms to solid. The solid state is highly unstable at ordinary conditions and easily transforms to liquid. Hence we say that mercury is a liquid.

state of any substance is determined at the room temperature,other metals are remain solid at the room temperature while mercury is liquid at the room temperature.that's why mercury is considered as liquid.

we classify matter on the physical appearance in three states-solid,liquid and gas.if we talk about mercury ,it is fluid in nature i.e it can flow.(liquids are fluid in nature).so, we can say mercury is a liquid.as far as your question of changing it in solid is concerned ,the answer is that when we decrease the temperature of liquid the intermolecular force become strong&hence liquid state can be converted into solid.

Mercury becomes a solid metal at -38.9° F. The temerature that controls what is called a liquid, solid or gas is 68°F.

we call anything solid,gas or liquid it is the condition of the thing at normal temperature.mercury is liquid at normal temperature.why we call water liquid though we can make it ice by decreasing temperature.it's the same thing.

any element is known by its property at room temperature.
at room temperature mercury is liquid and gold is solid so they are known as liquid and solid respectively.
every element changes its properties with temperature so it is identified the properties which it shows at room temperature.
