If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?
The temperature at which the substance boils is the temperature at which it boils. It's not the temperature at which any certain amount of it boils.
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.
When does a substance donot change its temperature even if it is heated?
During a phase change, a substance will remain at a constant temperature while it is being heated. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
How do you keep water heated to a constant temperature?
if u put it in the fridge or leave it somewhere where its the same temp.
The phase of matter can be changed by?
changing the temperature or surrounding pressure of a substance
Why does the temperature remain constant when it boils?
A substance has different phases, but it only boils at a certain temperature. If it is over that temperature it will evaporate or if it is under that temperature it won't boil.
Why liquid boils at constant temperature at a given temperature?
Yes.
If the boiling point of a certain amount of a liquid is 150 degrees then what is the boiling point of twice that amount of the liquid?
The temperature at which the substance boils is the temperature at which it boils. It's not the temperature at which any certain amount of it boils.
A pure substance boils only at a certain temperature which is called its?
boiling point.
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.
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 happens to the saturation temperature of the liquid refrigerant inside a refrigerant tank during system charging?
multiple choice: A: It rises B: It falls C: It remains constant D: It rises slightly, then remains constant. The answer is B The Vapor leaving the refrigerant tank is replaced by the liquid that boils off into vapor as the vapor being charged leaves the tank. The liquid saturation temperature drops as liquid boils to vapor. Example; The frost on a propane tank when you BBQ or use alot of propane for ???.
What temperature does every pure substance boil at?
it boils at about 100 degrees celcious ;) lolz

Why does the water in the pressure cooker boils even if the flame is put off?
The temperature remains high for a while.
