The lower heating value of Methanol is between 643 and 652 Kjoule/mole, calculated for open combustion (GREET 1.8) or human energy expenditure (Weir, corrected for nitrogen).
The higher heating value, including heat in watervapor produced, is found in tables to be between 726 and 733 KJoule/mole.
Different sources give slightly different values.
The conductivity of methanol is relatively low compared to other solvents. It is a nonpolar solvent with weak electrical conductivity due to the lack of ions or charged particles that can carry electrical current.
Use a beaker of water and test-tube with methanol. Place the beaker on a electric heater whose power you know. Place a thermometer in the test-tube
First measure the mass of the water and the methanol.
Then, start the heating process until the temperature becomes constant. Then time for say: 30s, and after this, stop the process.
Measure the current mass.
This means that in 30s, m grams of methanol has evaporated.
Energy = Power * 30
mL=Power*30
L=(Power*30)/m
Hope this helps..
About 1.40 kJ/kg-C depending on the temperature. http://www.engineeringtoolbox.com/methanol-properties-d_1209.html

What compounds are found in methanol?
Methanol is a simple alcohol compound made of carbon, hydrogen, and oxygen atoms. Its chemical formula is CH3OH.
Is methanol a solid?
Methanol is a colorless liquid at room temperature, with a melting point of -97.6°C. It is not a solid at standard conditions.
Will methanol melt ice?
Methanol can indeed lower the freezing point of water, making it effective at melting ice. It is commonly used as a de-icer for this reason. However, because methanol is toxic, it is not recommended for household use.
What is the compound formed after plunging a heated copper wire into a methanol?
When a heated copper wire is plunged into methanol, copper methoxide is formed. This is a compound that consists of copper, carbon, hydrogen, and oxygen atoms. It is produced through a redox reaction between copper and methanol.
Ethanol containing some methanol is called?
Ethanol containing some methanol is called adulterated ethanol. Methanol is a toxic compound that can have harmful effects if consumed in high quantities. Industries or individuals may add methanol to ethanol for various reasons, but it is illegal and dangerous due to the health risks associated with methanol consumption.
Why does methanol alcohol have low conductivity?
Methanol has low conductivity because it does not ionize well in solution. Methanol molecules do not easily dissociate into ions in water, resulting in fewer charged particles available to carry electrical current. Additionally, methanol is a nonpolar molecule, which further limits its ability to conduct electricity.
Why would someone test electrical conductivity with a solution containing both methanol and water?
Methanol can help increase the solubility of certain compounds compared to water alone. Testing conductivity in a mixture of methanol and water can help determine the presence of ions or charged particles in the solution, as both methanol and water can facilitate the movement of ions and enhance conductivity.
Do aqueous methanol have the same conductivity values as aqueous sucrose?
No, aqueous methanol is a polar solvent and will have higher conductivity compared to aqueous sucrose which is a non-electrolyte. Methanol dissociates into ions when dissolved in water, allowing it to conduct electricity, while sucrose remains a molecular compound and does not dissociate into ions.
Which is the better conductor CH3OH or KOH?
KOH (potassium hydroxide) is a better conductor than CH3OH (methanol) because KOH dissociates into ions more readily in solution due to its ionic nature, allowing for better conduction of electricity. Methanol does not dissociate into ions as effectively as KOH, leading to lower conductivity.
How does methanol react with water?
Methanol is miscible with water, which means it can mix in any proportion. When methanol is added to water, it forms a homogenous solution due to hydrogen bonding interactions between the methanol and water molecules. This allows methanol to dissolve easily in water.
What is woods alcohols chemical name?
methanol CHO
Is methanol a acid or base?
Methanol is a neutral compound and is neither classified as an acid nor a base.
What compounds are found in methanol?
Methanol is a simple alcohol compound made of carbon, hydrogen, and oxygen atoms. Its chemical formula is CH3OH.
Is methanol part of an aqueous solution?
Yes, methanol can be part of an aqueous solution. Methanol is soluble in water, so it can form a homogeneous mixture when mixed with water.
How many liters in one ton of methanol?
One liter of methanol is about 0.8 kg. One tonne of methanol is 1000 kg. Therefore one tonne pf methanol is about 1250 liters
Is water heavier than methanol?
No, water is heavier than methanol. Water has a higher density compared to methanol, which means that for the same volume, water will weigh more than methanol.
Is zinc soluble in methanol?
Yes, Zinc is soluble in Methanol and Glycerol
