Wood had heat of combustion of 14.84 kJ/kg, rough estimate of a match would weight about 0.12 g (assume dimension of 2mm x 2mm x 30 mm) and would contain only 1.78 kJ of energy when combusted with air. This same amount of energy is equivalent to 6 cc of boiling water (refer to room temperature of 25 C). Though not state the quantity of boiling water but it could say that a cup (250 cc) of boiling water had 44 time more energy than a match stick.
What else can I help you with?
What form of energy does a saucepan boiling on the stove use?
The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
What has more thermal energy a cup of boiling water or a pot of boiling water?
A pot of boiling water has more thermal energy than a cup of boiling water because it contains a greater volume of water and therefore a higher total amount of heat energy.
Does Boiling Water increase heat energy?
Boiling water involves converting liquid water to steam by adding heat energy. The heat energy increases the temperature of the water until it reaches its boiling point, at which point the water vaporizes into steam.
What energy does boiling water use?
Boiling water typically uses thermal energy, which is the energy associated with heat. When water reaches its boiling point, the thermal energy added to the water causes the water molecules to gain enough kinetic energy to break free from their liquid state and change into vapor.
What energy transformation is in a boiling pot of water?
The energy transformation in a boiling pot of water is from thermal energy (heat) to kinetic energy (movement of water molecules) as the temperature rises and water molecules gain enough energy to escape as water vapor.
What form of energy does a saucepan boiling on the stove use?
The heat energy from the stove, which in turn comes from the burning of the chemical energy in the gas that is burning, or from the electrical energy, depending on the type of stove.
Why does water put out burning wood?
The burning wood needs heat and oxygen as fuel. When burning wood has heat it has energy and water can quickly deprive the wood of its energy. When water comes in contact with the burning wood it takes the heat and the water turns into water vapor, a gas. The gas rises, and therefore, the heat is quickly taken from the burning wood. This is all due to water having a low boiling point. Imagine pouring water on the burning wood. Steam and smoke is produced, which is the water taking the heat into the sky, extinguishing the fire.
What has more thermal energy a cup of boiling water or a pot of boiling water?
A pot of boiling water has more thermal energy than a cup of boiling water because it contains a greater volume of water and therefore a higher total amount of heat energy.
Does Boiling Water increase heat energy?
Boiling water involves converting liquid water to steam by adding heat energy. The heat energy increases the temperature of the water until it reaches its boiling point, at which point the water vaporizes into steam.
Would burning of matchstick be a chemical reaction?
Yes, burning a matchstick is a chemical reaction because it involves the breaking and forming of chemical bonds. The reactants (matchstick and oxygen) are transformed into new substances (carbon dioxide, water vapor, and smoke).
What energy does boiling water use?
Boiling water typically uses thermal energy, which is the energy associated with heat. When water reaches its boiling point, the thermal energy added to the water causes the water molecules to gain enough kinetic energy to break free from their liquid state and change into vapor.

The energy transformation in a boiling pot of water is from thermal energy (heat) to kinetic energy (movement of water molecules) as the temperature rises and water molecules gain enough energy to escape as water vapor.
Which of the following is a physical change A. rusting of ironB. boiling of waterC. cooking of foodD. burning of wood?
Boiling of water
What is a change of state taking place toasting bread melting ice boiling potatoes buttering bread dissolving sugar into water boiling water burning coal or frying an egg.?
Toasting bread, burning coal, frying an egg: chemical changes.Melting ice, boiling potatoes, buttering bread, dissolving sugar into water, boiling water: physical changes.
When a stove is boiling water what type of energy transformation occurs?
When a stove is boiling water, electrical energy from the stove is being transformed into thermal energy as the stove heats the water. The thermal energy then causes the water to boil and turn into steam.
Is boiling water endothermic or exthermix?
Boiling water is endothermic as the water needs to take in energy from its surrounding in order to boil.
What requires more energy melting or boiling?
Melting requires energy input or absorption because liquid water has more energy than solid water.
