Different chemical reactions take different amounts of what?
thermal energy
What converts chemical energy to thermal energy?
chemical energy in batteries to thermal energy.
How is exothermic reactions related to chemical energy?
Heat energy is directly related to chemical interactions. As heat energy increases, chemical interactions also will due to the increased kinetic energy and therefore interactions of particles.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Why are endothermic reactions rare?
Chemical reactions occur spontaneously when the free energy of the product is less than the free energy of the reactants. Free energy is a combination of thermal energy (heat) and entropy. If thermal energy is absorbed during a reaction, there must be an exceptionally large increase in entropy to give a net reduction in free energy.
What process that converts chemical energy to thermal energy?
Combustion! and chemical reactions to pizza
Different chemical reactions take different amounts of what?
thermal energy
Why is burning of gas considered a chemical change?
All burning reactions involve chemical reactions (chemical changes).
What chemical reaction release thermal energy?
only nuclear reactionsChemical reactions that release free energy are called exergonic reactions. Fire and cellular respiration are examples of exergonic reactions.
What converts chemical energy to thermal energy?
chemical energy in batteries to thermal energy.
Does your body use chemical energy to generate thermal energy?
yes. the reactions that take place in our body, such as respiration, generate heat
What is the formula used to calculate thermal energy changes?
Simply use conservation of energy. The change in an object's thermal energy is equal to any heat (thermal) energy that gets into the object, minus any heat energy that gets out of the object. If you have energy conversion, such as chemical reactions, you need to account for the increase or reduction of heat energy due to those reactions, as well.
How is exothermic reactions related to chemical energy?
Heat energy is directly related to chemical interactions. As heat energy increases, chemical interactions also will due to the increased kinetic energy and therefore interactions of particles.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
What energy is in chemical reactions?
Chemical energy
Why are endothermic reactions rare?
