This is due to changes in energy. Look at the chemical reaction A + B --> C . Say it requires a lot of energy for A and B to react together, but very little energy to keep C as C. All the energy you put into the reaction to make A and B turn into C will be released as heat once C is formed. However if it requires a lot of energy to keep C as C after the reaction happens, then the reaction will seem cold because it is taking energy in the form of heat out of its surroundings!

∙ 12y agosome chemicals have their optimum temperature. that is where the chem works at it best, when the temp is taken up or down the chem doesnt work at its optimum best

What type of change will affect the state of matter but not its chemical makeup?
Temperature.
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.
Is temperature change chemical or mechanical?
chemical
How does the pH of juice change with time How does temperature affect the rate of chemical changes?

When you mix two substances in a beaker and expect them to undergo a chemical change the temperature of the mixture does not change has a chemical change occurred?
a chemical change occurs
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
Is temperature a chemical change?
Temperature change is not a chemical change.
How temperature affect chemical change?
it changed like house burning
What type of change will affect the state of matter but not its chemical makeup?
Temperature.
What type of change will affect the state of matter but it's chemical makeup?
Temperature.
How a temperature change is not a chemical change?
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
How does temperature affect the rate of a chemical change?
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
Do catalysts affect temperature?
A catalyst affects the speed of a chemical reaction. If the chemical reaction gives off heat, the reaction may affect the temperature, but the catalyst by itself doesn't affect the temperature.

How does temperature affect the chemical reactions of certain substances?
IT ACCELATATES THE CHEMICAL REACTIONS
Why does a chemical change in temperature indicate that a chemical reaction may have occurred?
A change of temperature implies that some energy has been transfered or used. Since chemical reactions either require or release energy to occur, the environment may change temperature as the substances react.
