What else can I help you with?
Energetically what must be done or what must happen before water can boil?
Before water can boil, energy in the form of heat must be applied to the water to raise its temperature to the boiling point, which is 100°C (212°F) at sea level. As heat is applied, the water molecules absorb the energy and become more energetic, eventually reaching a point where the hydrogen bonds holding the water molecules together break, resulting in the water transitioning from a liquid to a gas state known as steam.
Does a mix of coolant and water have a higher boiling point than water alone?
Yes. Water boils at 212 degrees. A 50/50 mix of water and antifreeze boils at 223 degrees. The temperature of the coolant can sometimes reach 250 to 275 F (121 to 135 C). Even with ethylene glycol added, these temperatures would boil the coolant, so something additional must be done to raise its boiling point. The cooling system uses pressure to further raise the boiling point of the coolant. Just as the boiling temperature of water is higher in a pressure cooker, the boiling temperature of coolant is higher if you pressurize the system. Most cars have a pressure limit of 14 to 15 pounds per square inch (psi), which raises the boiling point another 45 F (25 C) so the coolant can withstand the high temperatures. Antifreeze also contains additives to resist corrosion.
Can alcohol and water be seperated by physical means?
Sure! It's called distillation and it's done all the time, especially in Kentucky. Alcohol's boiling point is lower than water's is. If you heat an alcohol-water solution to alcohol's boiling point, the alcohol will boil off leaving the water behind.
Why did'NT the salt water boil faster tan the plain water?
Salt water has a higher boiling point than plain water because the presence of salt increases the water's boiling point. This means it requires more heat energy to reach boiling temperature, resulting in a longer time to boil compared to plain water.
Can you predict the boiling point of a substance under unchanging pressure?
No. Determining the boiling point at any pressure is normally done experimentally.

Why the separation 0f alcohol from water is done by distillation process?
because boiling point of watwer and alcohl is diffrent.
How is steam produced?
Steam is produced by boiling water to its vapor phase. This is typically done in a boiler by applying heat to the water, resulting in the water reaching its boiling point and turning into steam. The generated steam can then be used in various applications such as power generation, heating, or industrial processes.

What cooking is done by water vapour?
Boiling
Can carrots be done more quickly in vigorously boiling water than in water that is gently boiling?
Yes, carrots can be cooked more quickly in vigorously boiling water compared to water that is gently boiling. The higher temperature in vigorously boiling water allows the carrots to cook faster due to increased heat transfer and faster penetration of heat into the vegetable.
Why do you need to record the barometric pressure when calibrating the thermometer in the boiling water bath?
Recording the barometric pressure is important because it affects the boiling point of water. Variations in barometric pressure can lead to changes in the boiling point, which in turn can impact the accuracy of the calibration process for the thermometer. This information allows for adjustments to be made to ensure the calibration is done correctly.
How do you melt ice if the temperature is under 0 C?
The Celsius temperature scale is arranged by the boiling and freezing properties of water. The point at which water starts to freeze and ice starts to melt was labeled 0 degrees, and the point at which water boils was labeled 100 degrees.
What is the normal boiling point of ethanol?
The boiling point of ethanol whose boiling point is 78.3 degrees Celsius at 760 mm Hg at 650 mm Hg is going to be 75 degrees Celsius. This calculation is done using the clausius-clapeyron equation.
