Why are the temperatures of the melting point of ice boiling point of water called fixed point in calibrating the thermometer?
The temperatures of the melting point of ice and boiling point of water are called fixed points because they have well-defined and reproducible temperatures under standard atmospheric conditions. These fixed points provide reference temperatures that are used to calibrate thermometers and ensure accurate temperature measurements.
What type of object can hold boiling water and not melt?
Objects made of materials with high melting points, such as stainless steel, glass, or ceramic, can hold boiling water without melting. It's important to check the specific material's heat resistance before using it with boiling water.
What is the temperature of boiling water at sea level?
The temperature of boiling water at sea level is 100 The temperature of boiling water at sea level is 211.149°F.
Boiling point of water at sea level in Fahrenheit?
The boiling point of water at sea level is 212 degrees Fahrenheit.
What are some properties of molecular compounds?
Simple molecular structures like H2O and CO2 have the following properties: 1) Physical state: usually liquids and gases at room temperature due to weak intermolecular forces 2) Melting and boiling points: low (below 2000 C) melting and boiling points due to weak intermolecular forces 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble in water, but soluble in organic substances such as petrol Macromolecular structures such as diamond and SiO2 have the following properties: 1) Physical state: hard solids at room temperature due to the many strong covalent bonds holding the atoms together 2) Melting and boiling points: high melting and boiling points due to the many strong covalent bonds that must be broken before the substance can change state 3) Electrical conductivity: cannot conduct electricity because there are no free electrons 4) Solubility: insoluble
How does melting points and boiling compare to the characteristics of seal level of 0 celsius and 100 celsius?
At sea level, 1 atm, the melting point of water is 0 oC and the boiling point of water is 100 oC.
How do the melting and boiling points of water differ from those of a sugar water solution?
The melting and boiling points of water are higher than those of a sugar water solution because the presence of sugar disrupts the hydrogen bonding between water molecules. This disruption lowers the melting and boiling points of the solution compared to pure water.
What element has the highest melting and boiling points of all element?
Water it can melt in the boiling point and in the boiling point the water (ice) practically turns into a liquid (water) then into a gas
How do the melting and boiling points of water different from those of a sugar water solution?
it is pie
What are the freezing melting boiling and evaporation points of water?
The melting/freezing point of water is oC.The boiling point of water is 100 oC at standard pressure.Evaporation occur at any temperature.
Is Melting point higher than boiling points?
No, boiling points are always higher than melting points. When you turn a solid to a liquid, this process is called melting, and requires a lower temperature than boiling the substance. Take ice water for example. Ice becomes pure water at 0oC. The temperature needed to boil pure water is 100oC, which is a bigger number than zero.
How is the centigrade scale derived?
The centigrade scale is based on the melting and boiling points of pure water at 1 atmosphere of pressure. 0oC is the melting point and 100oC is the boiling point.
What is mean by melting and boiling point?
Melting point & boiling point means the temp that things melt & boil. Water's freezing & melting point is 32 degrees Fahrenheit or 0 degrees Celsius. The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. Different liquids or substances have different melting, freezing, and boiling points.
How can you tell that the melting of ice cube is a physical change?
You could test the resulting liquid by determining its boiling point and melting point. If they are the same as the boiling and melting points for water, then it is probably water and a physical change rather than a chemical change has occurred.
What are the properties of a ionic compound?
They are hard and brittle, conduct electricity in water, and have high melting and boiling points. (:
What are the freezing boiling and melting points of water?
The melting/freezing point of water is oC.The boiling point of water is 100 oC at standard pressure.Evaporation occur at any temperature.
What is wrong in choosing the melting point and the boiling point of water as standard fixed point?
The melting and boiling points of water change as the air pressure changes. For example, there is a certain air pressure in which steam, water and ice will stay like that forever.
