Carbon dioxide can be a solid, liquid or gas. At standard temperature and pressure it is a gas.
The element bromine is in the state of a liquid at room temperature (room temperature is roughly 20 degrees Celsius). This is because it's boiling point is 59 degrees Celsius, which is 39 degrees more then room temperature.
When an object is changing state form liquid to a gas the object is absorbing energy to allow its molecules to expand. it cant increase in temperature because it is using the energy that it is absorbing.

Liquid
Bromine is a halogen which can be a gas or liquid depending on the temperature. At room temperature bromine is a liquid metal.
Evaporation is the process where a liquid state changes from its LIQUID state to a GAS state.
the temperature at which a substance in the liquid state becomes a gas is a boiling point
RarefiedAmorphous, taking shape of the containerLower Density than solid or liquid of the same compound.Higher energy state than solid or liquid of the same material.Either the same temperature as the corresponding solid or liquid if both are present, or a higher temperature if only the gas is present.
NO!!! Boiling point is the temperature when a liquid changes to a gas. Melting point is the temperature when a solid changes to a liquid. Remember For rising temperatures It melts then boils For falling temperatures It condenses then freezes. Melting/Freezing point is the same temperature for change of state solid/liquid Boiling/Condensing point is the same temperature for change of state liquid/gas
In a word, temperature. A physical change will change the matter's state based on it's temperature. For example, water, H2O. You can increase the temperature to 212oF and it will change state from a liquid to a gas. You can decrease the temperature to 32oF and it will change state from a liquid to a solid. To answer your question, the process of doing so would be increasing or decreasing temperature of matter.
The same as with non-metals. The temperature at which liquid turns to gas, or gas to liquid.
Mercury is a liquid at room temperature.
a gas it becomes a gas at -42 C room temperature is 20 C
This temperature is the boiling point.
yes it does
It means whether the substance in question is solid, liquid or gas at normal room temperature, so you could assume that about 20 degrees celsius. Oxygen is a gas at room temperature Water is a liquid at room temperature Iron is a solid at room temperature.
The same substance can exist either as a solid, liquid or a gas and can change state depending on the temperature or external pressure.
