Which factor is responsible for water being a liquid rather than gas at room temperature?
The different states (which are solids, liquids and gases) are determined by the amount of energy present in the system. Energy is found in several forms, but kinetic energy is the form that the state of matter takes on, especially when it is changed from one state of matter to another. The various states of matter are always in constant motion. In liquids and gases, the motion known as the Brownian motion occurs. This is where particles move randomly while suspended. Even in solids, the particles continue to move, but is a vibration around a fixed point, and is not as free as the liquids and gases.
Hope that helped!! <(^_^)>

What intermolecular forces explain why water is a liquid at room temperature?
Hydrogen bonding is the intermolecular force responsible for water being a liquid at room temperature. The hydrogen bonds between water molecules are relatively strong, allowing them to remain in a liquid state rather than vaporizing at room temperature.
Boiling liquid maintains a constant temperature?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
The temperature at which a substance becomes a liquid?
It is different for different substances. the generic name for the temperature at which a solid becomes a liquid is the melting point. For a pure chemical compound or an element this is usually a sharp temperature rather than a range.
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
Is condensation a state of matter?
Condensation is a physical process in which a gas changes into a liquid state. It is not a distinct state of matter but rather a transition from a gas to a liquid at a particular temperature and pressure.

When a liquid is heated the temperature stops rising at the liquids what?
When a liquid is heated, its temperature will continue to rise until it reaches the boiling point of the liquid. Once it reaches this temperature, further heat added to the liquid will cause it to change into a gas rather than increase in temperature.
What happen to the temperature when ice is heated?
During a phase change (from solid to liquid, as in melting and also from liquid to gas as in boiling) the temperature remains constant, as all of the energy is going to affecting the change, rather than raising the temperature. Once it has changed from solid to liquid, the liquid can then raise in temperature.
Boiling liquid maintains a constant temperature?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
Why is that when a pure liquid is boiled its temperature remain constant?
The energy/heat being added to the liquid is used to convert the liquid into a gaseous state, rather than to heat the liquid (you get something similar when you melt ice). Once a gas, the temperature of the substance will start rising further if heat continues to be applied.
WILL liquid co2 boil at room temperature?
CO2 will not be a liquid at room temperature, rather a gas. It is only a liquid when compressed. Actually IF contained at high pressure it will be a liquid at room temperature ...It requires a combination of both pressure and temperature. It is a liquid in CO2 fire extinguishers and when the pressure is released some of it boils, absorbing a large amount of heat energy, more of it is released from the nozzle as a solid which then sublimes to forma gas.
The what remains constant when a liquid reaches boiling point?
The temperature. A liquid will increase in temperature until it reaches the boiling point temperature. At this temperature the liquid will become a gas. Under normal circumstances, the liquid cannot get any hotter than the boiling point without becoming a gas. So the liquid remains the same temperature until it has all boiled away.
The temperature at which a substance becomes a liquid?
It is different for different substances. the generic name for the temperature at which a solid becomes a liquid is the melting point. For a pure chemical compound or an element this is usually a sharp temperature rather than a range.

Why does not the temperature change during change of state from solid to liquid?
Addition of heat produces more liquid, breaking apart the intermolecular bonds, rather than increasing bond oscillation (increasing temperature).
