The temperature at which a given substance will change from a liquid into a gas?
The temperature in which a given substance will change from a liquid to a gas is its boiling point. Every element, compound and mixture has a different boiling point. Use an SI data book or the internet to find the boiling point of a particular suubstance.
Boiling and melting point of hydrogen?
melting: -259.14 °C boiling: -252.87 °C to find it in degrees F, multiply by 1.8 and then add 32.
What is the freezing and boiling point to glucose?
Melting (freezing) point: α-D-glucose: 146 °C β-D-glucose: 150 °C Glucose will decompose already below its boiling point, so there's no valued boiling point (at least not at normal pressure).
What is the melting point of samarium?
We find that samarium(III) oxide, disamarium trioxide or Sm2O3, has a melting point of 2335 °C and a boiling point of 4118 °C.
When an obtained melting point range is broad what does it tell about the substance?
strong intermolecular forces attract the molecules

What would be helpful to find the normal melting point and normal boiling point on a phase diagram?
Draw a vertical line through the triple point.
When an obtained melting point range is broad what does it tell about the substance?
strong intermolecular forces attract the molecules
Can you use oil bath for boiling point determination?
Oil baths will allow you to heat substances gently, but, the usual way of find out the boiling point of a substance is to heat it until it boils
On the basis of its boiling point identify the pure liquid as either ethyl acetate or butyl acetate?
To identify a substance, you must find more than its boiling point. Also look for its freezing point and density.
Is the melting point of organic compound high or low?
Melting point is important in organic chemistry because it can be used for the identification of a compound. For pure solid organic compounds will have a small melting point range (0.5-10C),thus presence of impurity can also be find out by Melting point.
How can you determine the melting point of a substance based in its heating curve?
Heating curves (temp vs time) show the transition of a solid to a liquid to a gas. The solid begins to absorb heat, which is represented by a gradual increase in your curve starting from the origin. Eventually, the solid will reach the melting point, at which the temperature will cease to increase until it has fully transitioned to a liquid phase. Therefore, the melting point is the y-value correspondind to the first horizontal portion of the heating curve.
A liquid unknown is insoluble in water and soluble in cyclohexane and alcohol with a boiling point of 145 C at 658 mm Hg. What is the substance?
To find the substance, you can use a Nomograph Table. Take the observed boiling point and the pressure to find the change in temperature correction. It was found that the actual boiling point was 3.5 degrees off what was stated, so the boiling temperature is 60.5 degrees Celsius. The compound has a boiling point of approximately 60.5 degrees (1) in water and (s) in cyclohexane and alcohol. Chloroform is extremely close to this, with its normal boiling point being 61 degrees Celsius and it matches everything else.
