Which has the lower freezing point oxygen or ethanol and why?
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
Why oxygen has a lower freezing point then ethanol?
Oxygen has a lower freezing point than ethanol because the molecular structure of oxygen is simpler, with weaker intermolecular forces between oxygen molecules compared to the ethanol molecules. This results in oxygen being a gas at room temperature and having a lower freezing point than ethanol, which is a liquid.
What happens to ethanol at C?
At 78.37°C, ethanol boils and undergoes a phase change from liquid to gas. It turns into ethanol vapor, which can be collected and condensed back into liquid ethanol through condensation.
What phase changes is exothermic?
2 phase changes that are exothermic are condensing and freezing.
What is the state of ethanol at -50 degrees celcius?
Ethanol at -50 degrees Celsius will be in a solid state, as its freezing point is around -114 degrees Celsius.
What happens to the freezing points as the ethanol concentration increased?
The answer depends on the substances in the mixture in which the ethanol concentration increases.
What is ethanol condensation point?
Ethanol has a condensation point of about 78.37°C (173.07°F) at standard atmospheric pressure. This is the temperature at which ethanol transitions from a gas to a liquid state.
Ethanol freezing point concentration?
The freezing point of ethanol decreases as the concentration of ethanol increases. Pure ethanol freezes at -114.1 degrees Celsius, while a 40% ethanol solution freezes at around -26 degrees Celsius. This is due to the phenomenon of freezing point depression, where the presence of solute particles in a solvent lowers the freezing point of the solution compared to the pure solvent.
How is thermal energy involved in the processes of freezing and condensation?
When thermal energy isreleased by the substance, it creates condensation and freezing process.
What is the freezing point for condensation?
Condensation does not have a specific freezing point as it is the process by which vapor turns into a liquid when it cools. However, condensation can lead to the formation of ice when the temperature drops below freezing.
Which has the lower freezing point oxygen or ethanol and why?
Oxygen has a lower freezing point than ethanol. This is because the intermolecular forces in oxygen molecules are weaker than in ethanol molecules, allowing oxygen to freeze at a lower temperature.
Is Freezing of ethanol endothermic or exothermic?
Freezing of ethanol is an exothermic process. During freezing, ethanol transitions from a liquid state to a solid state, releasing heat to the surroundings as the molecules arrange into a more ordered structure. This release of heat energy indicates that the process is exothermic.
Liquid turns into a solid?
Liquid solidifies through the removal of heat. This usually entails the lowering of temperature to the freezing point of that pure (or impure) substance. Impurities will lower the freezing point of liquid, and mixtures of substances will result in a range of freezing points.
What has a lower freezing point mercury or ethanol?
Ethanol has a lower freezing point than mercury. The freezing point of ethanol is around -114°C (-173°F), while mercury freezes at about -39°C (-38°F). This makes ethanol significantly more effective in applications requiring low temperatures, such as in antifreeze solutions.
Is the freezing point as the same condensation point?
no
Why oxygen has a lower freezing point then ethanol?
Oxygen has a lower freezing point than ethanol because the molecular structure of oxygen is simpler, with weaker intermolecular forces between oxygen molecules compared to the ethanol molecules. This results in oxygen being a gas at room temperature and having a lower freezing point than ethanol, which is a liquid.
Can you frezze everclear?
Ethanol's freezing point is -114.1
