The calorific value of naphthalene is approximately 25,800 kJ/kg. It is often used as a standard for measuring the energy content of other substances.
The lower calorific value or Net calorific value (NCV) which supposes that the products of combustion contain the water of combustion to the vapor state. The heat contained in this water is not recovered.The higher calorific value or Gross calorific value (GCV) which supposes that the water of combustion is entirely condensed. The heat contained in this water is recovered.sayed karar waris
Foam padding can have many uses. A foam pad for chairs and seating help to furnish the chair for better comfort. Foam padding can also be used under carpeting for walking.

calorific value means the total amount of heat energy evolved when 1gm of the fuel is completely burnt. from the combustion equation find out enthalpy of combustion.then divide the molecular weight to that quantity.
Foam is commonly used for dining chairs because it provides comfort and support for extended periods of sitting. Foam also helps to absorb shock and reduce pressure points, making it a more comfortable seating option. Additionally, foam is durable and can maintain its shape over time, making it a long-lasting choice for dining chairs.
The high heating value of rubber (8600 kcal / kg) is used to generate heat energy
The calorific value of LPG (liquefied petroleum gas) is usually around 46.1 MJ/kg, which is equivalent to approximately 12.8 kWh/kg. This value may vary slightly depending on the specific composition of the LPG being used.

The calorific value of lube oil typically ranges between 38 to 42 megajoules per kilogram (MJ/kg), depending on its composition and specific formulation. This value indicates the amount of energy released during the combustion of the oil. Lube oils are primarily used for lubrication and cooling in engines and machinery, and their calorific value can influence their performance and efficiency in certain applications.
The calorific value of paint can vary depending on its composition, but generally, it is not significant enough to be used as a reliable source of energy. Paint is not a common fuel source due to its limited energy content and potential environmental hazards associated with burning it.
Used banquet chairs are definitely a better value than new ones, especially if you plan to use them once or infrequently. There are also party/wedding services that will allow to borrow such chairs for a fee.
