What are the energy transformations in striking a match?
When striking a match, the chemical energy stored in the match-head is transformed into heat and light energy.
Is lighting a matchstick physical?
Yes, lighting a matchstick is a physical action that involves striking the match head against a rough surface to produce friction and heat, which ignites the match.
Why is work done in striking match?
When a match is struck, the friction between the match head and the striking surface produces heat, igniting the match head due to the heat-sensitive chemicals present. This process requires work to break the chemical bonds in the match head and generate enough heat for combustion to occur.
What is the energy transformations in a striking match?
When a match is struck, mechanical energy from the friction between the match head and the striking surface is converted into thermal energy from the heat production that ignites the match head. This thermal energy is then transformed into light and heat energy as the match continues to burn.
Is striking a match against a box an example of convection?
No, striking a match against a box is an example of friction creating heat. Convection involves the transfer of heat through the movement of fluid, such as air or water.
What does striking the match produce heat?
When a match is struck, the friction ignites the molecules on the match head, creating a chemical reaction that releases heat energy. This heat is then used to light the matchstick.
What are the energy transformations in striking a match?
When striking a match, the chemical energy stored in the match-head is transformed into heat and light energy.
Heat is given off when striking a match?
The friction creates the heat.
Is someone striking a match endothermic or exothermic?
Striking a match is an exothermic process because it releases heat and light energy as the match ignites. The friction created when striking the matchstick generates enough heat to ignite the chemicals on the match head, leading to a chemical reaction that releases energy in the form of heat and light.
Is lighting a matchstick physical?
Yes, lighting a matchstick is a physical action that involves striking the match head against a rough surface to produce friction and heat, which ignites the match.

No, striking a match against a box is an example of friction creating heat. Convection involves the transfer of heat through the movement of fluid, such as air or water.
What makes a match burn?
A match burns to produce fire. It burns because of the reaction between the sulfur in the match and the object it is striking.
Is striking a match to a Bunsen burner a chemical reaCTION?
Yes, striking a match to a Bunsen burner involves a chemical reaction. The match contains chemicals that react with oxygen in the air when ignited, producing heat and a flame.
What energy transformation strike the matchstick?
When a matchstick is struck, mechanical energy from the friction of striking is converted into thermal energy, which then ignites the chemicals on the match head to produce light and heat energy.
Which type of energy transformation is involved in a match being struck and lit?
The energy transformation involved in striking and lighting a match is primarily chemical to thermal energy. When the match is struck, friction creates heat, causing the chemicals in the match head to react and produce a flame, which is a release of thermal energy.
