What energy transfer happens when a candle burns?
When a candle burns, chemical energy stored in the wax is converted into heat energy and light energy through a chemical reaction called combustion. The heat energy causes the wax to melt and then evaporate, while the light energy is emitted as a flame.
What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
What is difference between released chemical energy and absorbed chemical energy?
When chemical energy is released, it is released to the environment in the form of heat. This heat can be felt and measured. When a reaction results in an increase in temperature, energy has been released (it gets hot), and you have an exothermic reaction. When chemical energy is absorbed, it is taken from the environment. This causes a decrease in the temperature of the surroundings. Energy has been absorbed from the environment around the reaction (it gets cold), and you have an endothermic reaction.
What chemical reaction called when it absorbs energy and causes decrease in temperature?
Probable you think to sweating.
What is a chemical reaction in which energy is absobed?
Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
Which energy causes endothermic reaction in photography?
The energy that causes endothermic reactions in photography is typically light energy. When light hits a photosensitive material such as film or a digital sensor, it triggers a chemical reaction that absorbs energy from the surroundings, resulting in the temperature dropping and an endothermic reaction occurring.
What causes water to evaporate into the atmosphere?
Heat energy.
How do you convert chemical energy in a battery to electrical energy?
Chemical energy in a battery is converted to electrical energy through a chemical reaction that occurs within the battery. The reaction causes a flow of electrons between the battery's two terminals, generating an electric current. This current can then be used to power electronic devices.
What is the difference between a exothermic chemical reaction and a endothermic chemical reaction?
energy released by the reaction or energy absorbed.
What is the source of energy for fire?
The source of energy for fire is typically heat, which causes a chemical reaction between a fuel source (such as wood or gas) and oxygen in the air. This reaction releases energy in the form of heat and light, sustaining the fire.
The energy necessary to start a chemical reaction?
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
How does a dynamite explosion convert chemical energy to mechanical energy?
The dynamite contains chemical energy stored in its molecular bonds. When the dynamite is ignited, a rapid chemical reaction occurs, releasing large amounts of heat and gas. This sudden increase in pressure and volume creates a powerful shockwave that produces mechanical energy, resulting in the explosion.
