How much energy per gram of hydrogen is produced when hydrogen gas is being burned?
The combustion heat of hydrogeh (HHV) for 1 g is 141,8 kJ.
What element produces the highest energy per gm after combustion?
Hydrogen produces the highest energy per gram after combustion, as it has the highest energy content per unit weight compared to other elements. When burned in the presence of oxygen, hydrogen releases a large amount of energy in the form of heat.
What fuel gives off the most heat per gram when burned?
Hydrogen fuel gives off the most heat per gram when burned, producing about 141.9 megoujoules (MJ) per kilogram. This high energy density is due to hydrogen's low molecular weight and its combustion reaction with oxygen, which produces water as a byproduct. In comparison, hydrocarbons like gasoline and natural gas yield less energy per gram, making hydrogen one of the most efficient fuels in terms of heat output.
What is the numerical specific heat of water?
The specific heat capacity of water is approximately 4.184 Joules per gram per degree Celsius (J/g°C).
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C?
The quantity of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius is defined as the specific heat capacity of that substance. It is measured in joules per gram degree Celsius (J/g°C) or in calories per gram degree Celsius (cal/g°C).
How much energy per gram of hydrogen is produced when hydrogen gas is being burned?
The combustion heat of hydrogeh (HHV) for 1 g is 141,8 kJ.
Which produces more heat a gram of candle wax or gram of alcohol?
A gram of candle wax produces more heat when burned compared to a gram of alcohol. Candle wax has a higher energy content per gram than alcohol, which results in more heat being released during combustion.
What element produces the highest energy per gm after combustion?
Hydrogen produces the highest energy per gram after combustion, as it has the highest energy content per unit weight compared to other elements. When burned in the presence of oxygen, hydrogen releases a large amount of energy in the form of heat.
How does heat combustion of paraffin compare to heat combustion of propane?
The heat combustion of paraffin produces less heat energy compared to propane because propane has a higher energy content per unit mass. Propane releases more energy per carbon atom compared to paraffin during combustion, making it a more efficient fuel for heating. Additionally, propane burns cleaner with lower emissions compared to paraffin.
What is the quantity of heat in joules or calories required to raise the temperature of 1 gram of a substance 1C.?
specific heat(; your welcome!
What is calirific value of heat?
The calorific value of a substance is the amount of heat released during the complete combustion of a unit quantity of that substance. It is usually expressed in units like calories or joules per gram or per mole. Knowing the calorific value of a substance is important for determining its energy content.
What is the specific heat capacity of argon?
The specific heat capacity of argon is 0.520 joules per gram per degree Celsius.
What is the numerical specific heat of water?
The specific heat capacity of water is approximately 4.184 Joules per gram per degree Celsius (J/g°C).
How do you convert joule per hour into joule per gram?
To convert joule per hour to joule per gram, you need a material's specific heat capacity. Multiply the joules per hour by 3600 (since there are 3600 seconds in an hour) to get joules per second. Then divide by the specific heat capacity of the material in joules per gram per degree Celsius to obtain joules per gram.
How do you calculate the heat of combustion in kJ/mol?
To calculate the heat of combustion in kilojoules per mole (kJ/mol), you can use the formula: Heat of combustion -H / n Where: H is the enthalpy change of combustion in kilojoules (kJ) n is the number of moles of the substance being combusted This formula helps determine the amount of heat released or absorbed during the combustion of one mole of a substance.
What is the expression and value for specific heat of water?
Specific heat of water is 1 calory per gram .
What is calorific value of heavy fuel oil?
It is the amount of heat produced by the complete combustion of a unit weight of fuel. Usually expressed in calories per gram or BTU's (British Thermal Units) per pound, the latter being numerically 1.8 times the former.
