Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
Can sensible heat and latent heat transfers be read with a thermometer?
A thermometer measures sensible heat transfer, which is the heat transferred that causes a change in temperature. Latent heat transfer, on the other hand, involves the heat absorbed or released during a phase change (such as melting or boiling) and cannot be directly measured by a thermometer.
How Will You Calibrate a thermometer in degree Celsius.. ..?
The thermometer was used by the originators of the Fahrenheit and Celsius scales.Anders Celsius, a Swedish Astronomer, devised the Celsius scale, which was described in his publication the origin of the Celsius temperature scale in 1742.Celsius used two fixed points in his scale: the temperature of melting ice and the temperature of boiling water. This wasn't a new idea, sinceIsaac Newton was already working on something similar. The distinction of Celsius was to use the melting temperature and not the freezing temperature. The experiments for reaching a good calibration of his thermometer lasted for 2 winters. By performing the same experiment over and over again, he discovered that ice always melted at the same calibration mark on the thermometer. He found a similar fixed point in the calibration of boiling water vapour (when this is done to high precision, a variation will be seen with atmospheric pressure). At the moment that he removed the thermometer from the vapour, the mercury level climbed slightly. This was related to the rapid cooling (and contraction) of the glass.The air pressure influences the boiling point of water. Celsius claimed that the level of the mercury in boiling water is proportional to the height of the barometer.When Celsius decided to use his own temperature scale, he originally defined his scale "upside-down", i.e. he chose to set the boiling point of pure water at 0 °C (212 °F) and the freezing point at 100 °C (32 °F).[1] One year later Frenchman Jean Pierre Cristin proposed to invert the scale with the freezing point at 0 °C (32 °F) and the boiling point at 100 °C (212 °F). He named it Centigrade.[2]Finally, Celsius proposed a method of calibrating a thermometer:Place the cylinder of the thermometer in melting pure water and mark the point where the fluid in the thermometer stabilises. This point is the freeze/thaw point of water.In the same manner mark the point where the fluid stabilises when the thermometer is placed in boiling water vapour.Divide the length between the two marks into 100 equal pieces.These points are adequate for approximate calibration but both vary with atmospheric pressure. Nowadays, the triple point of water is used instead (the triple point occurs at 273.16 kelvins (K), 0.01 °C).
What is argon degrees Celsius?
I guess the question is supposed to be either the melting point or boiling point of argon in degree Celsius. If so, the answer are: Melting point = −189.34 °C Boiling point = −185.848 °C
Why doesn't the thermometer measure latent heat?
A thermometer measures temperature by detecting the average kinetic energy of the particles in a substance, rather than the energy involved in phase changes, such as latent heat. Latent heat is the energy absorbed or released during a phase change, like melting or boiling, and does not directly affect the average kinetic energy of the particles that the thermometer detects.
How are plastics catergorised?
They are classified according to their strength, rigidity, plasticity, and boiling/melting temperatures. They are classified according to their strength, rigidity, plasticity, and boiling/melting temperatures.
Are melting and boiling point physical properties of a substance?
Yes, melting and boiling points are physical properties of a substance. They represent specific temperatures at which a substance transitions from one phase to another - solid to liquid for melting point, and liquid to gas for boiling point.
What is the boiling point of water in degrees Celsius on a thermometer?
The boiling point of water is 100 degrees Celsius and the melting point of water is 0 degrees Celsius
Is boiling point is always same as the melting point?
No, the boiling point and the melting point are not always the same. The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid.
How a thermometer helps you compare the energies of particales?
A thermometer doesn't actually measure the heat ENERGY in the molecules, instead it just compares the HOTNESS and COLDNESS with the melting and boiling point of water or any two other important temperatures. Heat energy is measured in joules and temperature is measured inCelsius,Fahrenheit, or kelvin.
How are the initial and final temperatures of the melting range determined?
By melting and determinating the answers between the boiling and freezing of condensated water or other form of liquid.
Are water's melting and boiling temperatures higher lower or average compared to other liquids?
This is only a relative appreciation.
Does melting and boiling cause physical changes?
Melting and boiling are physical changes.
What is the boiling point of magnetite?
Magnetite does not have a specific boiling point as it decomposes before reaching its melting or boiling point. Magnetite decomposes into iron(II) oxide and eventually into iron oxide and oxygen at high temperatures.
Are the boiling points higher temperature than the melting points?
yes, for the same molecule. However, some substances don't have a liquid phase and so the melting point is exactly the same as the boiling point at normal pressures (sublimation is the phase change from solid -> gas)
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
What is hydrogen's melting and boiling point?
Melting: -259.14 C Boiling: -252.87 C
