What is the difference between boiling water and decomposing water?
Boiling water is the process in which water reaches its boiling point and turns into vapor, while decomposing water involves breaking down water molecules (H2O) into its constituent elements, hydrogen and oxygen. Boiling water is a physical change, while decomposing water is a chemical change. Boiling water is reversible, while decomposing water is typically irreversible.
What layer is five times hotter than boiling water?
The layer that is five times hotter than boiling water is the outer core of the Earth. While boiling water reaches temperatures of around 100 degrees Celsius (212 degrees Fahrenheit), the outer core is believed to have temperatures ranging from approximately 4,000 to 6,000 degrees Celsius (7,200 to 10,800 degrees Fahrenheit). This extreme heat is primarily due to the presence of molten iron and nickel, along with the intense pressure at that depth.
Which has the higher temperature - boiling water or ice?
Boiling water has a higher temperature than ice. Boiling water is heated to 100 degrees Celsius (212 degrees Fahrenheit), while ice is typically at 0 degrees Celsius (32 degrees Fahrenheit).
Did the temperature change while the water was boiling?
Yes
What is the difference between dew and steam?
Dew is formed when water vapor in the air condenses onto a cool surface, such as grass or leaves, whereas steam is water vapor that is produced when water is heated to its boiling point. Dew usually forms overnight or early in the morning, while steam is typically seen when cooking or boiling water.
Why does the ice take a long time to melt though the water at the top of the test tube is boiling?
The ice takes a long time to melt even when the water at the top of the test tube is boiling because heat transfer occurs mainly from the boiling water to the ice through conduction, which is relatively slow. The boiling water's heat must first travel through the water layer above the ice before reaching the ice itself. Additionally, the large temperature difference between the boiling water and the ice means that heat transfer is not as efficient. Therefore, while the water is boiling, the ice remains relatively insulated from the heat, causing it to melt slowly.
Water vapor and steam are the same thing?
Yes, but that stuff you can see isn't steam. Neither steam nor water vapor are visible. The could of white stuff you can see above a boiling kettle is water droplets formed by the condensation of the water vapor/steam as it collides with the cooler air outside the kettle.
How do the boiling points of water and ethanol compare?
The boiling point of water is higher than the boiling point of ethanol. Water boils at 100 degrees Celsius, while ethanol boils at 78.37 degrees Celsius.
Does salt evaporate in boiling water?
No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.
Why is more heat needed to vaporize water than gasoline?
Gasoline has a less boiling point (72 degree Celsius) While water has a bigger boiling point (100 degree Celsius)
When boiler pressure increases what happens to the boiling point of water?
The boiling point of water is dependent on environmental factors and the presence of solutes. In this case the pressure of the system on the water serves to increase the boiling point of water. The higher pressures increase boiling points while lowering pressure decreases it.
What has a higher boiling point alcohol or water?
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
