How is cooking sausage a chemical change?
Cooking sausage is a chemical change because the heat from cooking causes chemical reactions to occur in the sausage. These chemical reactions change the composition of the sausage, leading to the browning of the meat, alteration of flavors, and changes in texture.
Is grilling of milkfish a chemical or physical change?
Grilling milkfish is a chemical change because the heat causes the proteins in the fish to denature and undergo chemical reactions that change its composition and flavor.
What type of chemical change produces heat?
Exothermic reactions. E.g. combustion, oxidation
What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
Is toasting bread a chemical change or a physical change?
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
Heat exchange in chemical reactions is due to a change in what?
Enthalpy-The heat added to or loss by a system at constant pressure

Why is temperature not a chemical change?
Temperature change, more accurately, a change in heat, is not a chemical change because it does not happen on a chemical level. Heat is the product of varying levels energy, not physically tangible particles. The higher the energy the higher the heat. To clear up any further confusion, a lot of people think heat is a chemical process, but it's not. Most people that think this, do so because the first way most of us imagine this change is through exothermic (reactions that create heat) reactions which are chemical processes like explosions.
What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
Is toasting bread a chemical change or a physical change?
Toasting bread is a chemical change because the heat causes chemical reactions to occur within the bread, leading to a browning effect and changing the chemical composition of the bread.
What is thermochemical equation?
A thermochemical equation is a balanced chemical equation that includes the energy change (in the form of heat) associated with the reaction. It shows the enthalpy change of the reaction, indicating whether heat is absorbed (endothermic) or released (exothermic) during the process.
The type of chemical change that absorbs heat energy?
Endothermic reactions are the type of chemical changes that absorb heat energy from their surroundings. In these reactions, the products have higher energy content than the reactants, resulting in a decrease in temperature in the surrounding environment.
Is it a chemical reaction if you but copper in a fire and it turns black?
yes it is a chemical reaction because the change involved heat and all chemical reactions involve heat and a difference in the appearence of the substance which has recieved heat is noticed
When rocks undergo metamorphic changes chemical reactions cause minerals to recrystallize or change form which agent provides the energy for these reactions?
Heat
Do chemical reactions need heat to start them off?
Endothermic reactions need heat.
