What four elemental substances exist in the liquid state at or near room temperature?
Mercury and bromine are both liquid at what is commonly considered room temperature. Gallium and caesium both melt at above room temperature but below normal human body temperature, while rubidium melts just above normal human body temperature. Francium would have a melting point below caesium's (but probably above normal room temperature) if you could collect enough of it in one place to actually see and keep it from vaporizing your laboratory (it's pretty highly radioactive, and chemically reactive to boot; caesium and rubidium are also highly chemically reactive).

Which form of sulphur exist at room temperature?
elemental sulfur (yellow solid)
What substances are liquid at room temperature 293 k?
At room temperature (approximately 293 K or 20 °C), several substances are in a liquid state. Common examples include water, ethanol, and benzene. Additionally, some oils, like olive oil and motor oil, remain liquid at this temperature. Many organic solvents, such as acetone and chloroform, also exist as liquids at room temperature.
Most substances that have molecules with approximately the same weight as water molecules are gases at room temperature. Water is a liquid at room temperature. Water is a liquid at room temperature be?
...because water molecules have strong intermolecular forces (hydrogen bonding) holding the moelcules together in the liquid state. Most other substances with similar molar mass do not exhibit hydrogen bonding, and thus they exist as gases.
What elements exist in liquid form?
Elements such as mercury and bromine exist in liquid form at room temperature. Mercury is a transition metal that is liquid at room temperature, while bromine is a nonmetal that is also liquid at room temperature.
How do you change Mercury powder into liquid Mercury?
Mercury powder does not exist; elemental mercury is a liquid metal at room temperature and cannot be turned into a powder. Mercury is transformed into a liquid by applying heat to raise its temperature above its melting point of -38.83°C.

Do all substances exist in a solid liquid or gaseous state?
Yes
How do you change Mercury powder into liquid Mercury?
Mercury powder does not exist; elemental mercury is a liquid metal at room temperature and cannot be turned into a powder. Mercury is transformed into a liquid by applying heat to raise its temperature above its melting point of -38.83°C.
Elements and substances can exist in these forms of matter?
Solid, liquid, gaseous and plasma.
Which substances exist in three forms of matter simultanously at room temperature?
They are what you call Halogens.The halogens exist ,at a room temperature,in all three states of matter: Solid-Iodine,Astatine; Liquid-Bromine; Gas-Fluorine,Chlorine;
Is there any substance like water which can take the shape of liquid gas and solid?
Yes, there are some substances like carbon dioxide and ammonia that can exist as a liquid, gas, and solid at different temperatures and pressures. These substances undergo changes in state based on variations in temperature and pressure.
Why do substances exist as gases?
At a given temperature practically all substances become a gas; it is a change of phase.
What are two elements in the periodic table that exist as liquid?
All elements can exist as liquids at some temperature or other. At standard room temperature, only bromine and mercury are liquid. However, gallium has a melting point of only 29.76 degrees C (85.57 degrees F) which is not far above standard room temperature, and can occur naturally in some places.
