Want this question answered?
a gas it becomes a gas at -42 C room temperature is 20 C
ethanol Edit- this would be methanol because ethanol is a 2-carbon chain compared to the 1C in ethanol, and therefore has more intermolecular forces. As a result, molecules of ethanol would need more energy to break these intermolecular forces to be in a gaseous phase.
Yes, only if the temperature of a substance is increased.
The temperature of the environment and the melting and evaporation temperature of the substance.
Ethanol (the kind of alcohol you get in drinks) is liquid at room temperature. It boils at around 78'C, so will become a vapour at this point.
Ethanol is indeed a liquid at standard temperature and pressure.
At room temperature ethanol is a clear, volatile liquid.
Liquid.
-114 degrees C
It is a liquid because at room temperature the molecular structure of the substance wants to expand. When the substance expands it goes from being a solid to a liquid. This expansion takes place when the room is at the commonly know "room temperature"
a gas it becomes a gas at -42 C room temperature is 20 C
depends of the substance
The amount of a substance that a liquid holds will be the solubility of that substance in that volume of the liquid - at that temperature.
