A pure substance can boil at -100°C if its boiling point is indeed at that temperature under standard atmospheric pressure. For example, substances like liquid nitrogen boil at -196°C, while others, like certain hydrocarbons, may have boiling points that are higher. The boiling point of a pure substance is determined by its molecular structure and intermolecular forces. Therefore, whether a pure substance boils at -100°C depends on its specific properties.
What else can I help you with?
What boils at what degree Celsius?
This question is too vague to answer: many different substances boil at many different degrees Celsius. In fact the same substance can be made to boil at different temperatures by changing the pressure acting on it.
Does a pure substance always boil at a fixed temperature?
Yes, a pure substance boils at a fixed temperature under a specific pressure. This boiling point is characteristic of the substance and remains constant as long as the pressure is maintained. However, if impurities are present or if the pressure changes, the boiling point can vary.
How does the temp of water change as it boils?
Water stays at a constant temperature when it boils unless it is under pressure. More heat just makes it boils faster. The boiling temperature is around 212F or 100C varying somewhat with the altitude and the purity of the water.
Is a lemon a pure substance?
it is a pure substance.... not
Is Methane a mixture or a pure substance?
Methane is a pure substance.
A pure substance boils only at a certain temperature which is called its?
boiling point.
What happens at 0c and 100c?
0 C is 0 degrees Celsius. Pure water freezes at this temperature. 100 C is the temperature when pure water boils at sea level.
When water boils at 100c is that example of chemical property?
No, boiling point is a physical property of a substance, not a chemical property. Chemical properties describe how a substance interacts with other substances to form new substances.
Can you tell if a liquid is a pure substance or a solution by looking at it?
No. On the visible and even the microscopic level a solution is indistinguishable from a pure substance.
What boils at what degree Celsius?
This question is too vague to answer: many different substances boil at many different degrees Celsius. In fact the same substance can be made to boil at different temperatures by changing the pressure acting on it.
A pure substance boils only at a certain temperature?
Each liquid boils at a different temperature, but the temperature it boils at is called the Boiling Point. For example, the boiling point of water is 212 Fahrenheit.This specific temprature is dependant on the pressureon the liquid at that time, as an example at ahigher temperatures the boiling point is higher.
What will be the pH of pure water?
At 100C the pH of pure water is 6.14 which is neutral
What temperature in degress celsius does water freeze and boil?
it freezes at 0C and boils at 100C
Is 130 c hot or cold?
130c is very hot (water boils at 100c)
How can you tell a pure substance from a mature by its boiling point?
take water for example, if water boils at 100 degrees Celsius then it is pure. if the boiling temperature turns out to be higher or lower (most of the time it is higher) then a substance is impure. salt water boils at 102.8 degrees Celsius.
How you would determine that the distilleate collected is a pure substance?
Pure Substances Boil at a Constant Temperature while Mixtures do not, To determine if the Distillate is pure the Liquid distillate would be boiled and for example if the substance is water, it should begin boiling at exactly at 100 degrees celcius if it boils below or above that point it is not a pure substance
What temperature does every pure substance boil at?
The boiling temperature of a pure substance is unique and specific to that substance. It is determined by its molecular structure and strength of intermolecular forces. This characteristic boiling temperature is referred to as the substance's normal boiling point.
