What else can I help you with?
When a substance gives off or absorbs heat is that a sign that describes a sign of a chemical change occurring?
Yes, if a substance gives off or absorbs heat, it could be a sign that a chemical change is occurring. This process is known as an exothermic or endothermic reaction, respectively, which are common indicators of chemical reactions.
What are some examples of chemical energy conv erted into light energy?
Fire The wood is a chemical energy and the fire (gasoline) is a chemical energy the heat from the fire obviously gives off heat and the "crackles" you hear gives off sound energy and the flame gives off light energy
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Which type of reaction gives off heat?
An exothermic reaction gives off heat as a result of energy being released in the form of heat. In an exothermic reaction, the products have lower energy than the reactants, leading to the release of heat to the surroundings.
What is a chemical reaction gives off heat called?
exothermic reactions-gives off heat
A chemical reaction that gives off heat is most likely to be what?
An endothermic reaction is one that consumes heat.
If a physical or chemical change gives off heat energy it is?
an exothermic process
When a substance gives off or absorbs heat is that a sign that describes a sign of a chemical change occurring?
Yes, if a substance gives off or absorbs heat, it could be a sign that a chemical change is occurring. This process is known as an exothermic or endothermic reaction, respectively, which are common indicators of chemical reactions.
During photosynthesis what chemical reaction gives off heat?
During photosynthesis, no chemical reaction gives off heat. Photosynthesis is an endothermic process, meaning it requires energy in the form of sunlight to convert carbon dioxide and water into glucose and oxygen.
What are some examples of chemical energy conv erted into light energy?
Fire The wood is a chemical energy and the fire (gasoline) is a chemical energy the heat from the fire obviously gives off heat and the "crackles" you hear gives off sound energy and the flame gives off light energy
Does the burning of a candle give off or absorb heat?
The burning of a candle gives off heat. This is because the chemical reaction of the wax with oxygen releases energy in the form of heat and light.
What is a reaction called that gives off heat?
exothermic reactions-gives off heat
When a chemical reaction takes in more energy than it gives off it becomes what?
When a chemical reaction takes in more energy than it gives off, it becomes an endothermic reaction. In an endothermic reaction, energy is absorbed from the surroundings in the form of heat.
What energy does a flash light have It has light heat and chemical Light because that's what it gives off Heat cause when turned on it starts giving heat and chemical because the battery consists of c?
The batteries in the flashlight store chemical energy. Once you turn the flashlight on, this chemical is converted into light and heat energy.
Is giving off light a physical or chemical change?
I would think it to be a Physical Change. Not chemical.
Could you please use the word exothermic in a sentence?
"This chemical reaction gives off a lot of heat; it must be exothermic"
