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!

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
Which type of change will affect the state of matter but not its chemical makeup?
A change in temperature or pressure can affect the state of matter without altering its chemical composition. For example, melting ice to form liquid water or boiling liquid water to form steam are changes in state of matter that do not change the chemical makeup of water molecules.
What type of change will affect the state of matter but not its chemical makeup?
A change in state of matter, such as melting, freezing, or boiling, will affect the arrangement of particles without changing the chemical composition of the substance. For example, ice melting into water involves a change in state from solid to liquid, but the chemical makeup of water remains the same (H2O).
How does the pH of juice change with time How does temperature affect the rate of chemical changes?
The pH of juice can change over time due to chemical reactions such as oxidation and fermentation. Higher temperatures generally increase the rate of chemical reactions, so temperature can affect the rate at which the pH of juice changes. Higher temperatures can lead to faster degradation of components in juice, which can impact its pH.
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?
No, temperature is not a chemical change. Temperature is a measure of the average kinetic energy of particles in a substance and does not involve the rearrangement of atoms or formation of new substances.
How temperature affect chemical change?
it changed like house burning
What type of change will affect the state of matter but it's chemical makeup?
Temperature.
What is the impact of a change in temperature on the delta S of surroundings in a chemical reaction?
A change in temperature can affect the entropy change (delta S) of the surroundings in a chemical reaction. When the temperature increases, the surroundings absorb more heat energy, leading to an increase in entropy. Conversely, a decrease in temperature results in a decrease in entropy of the surroundings.
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 a change in temperature affect the equilibrium shift of a chemical reaction?
A change in temperature can affect the equilibrium shift of a chemical reaction by either favoring the forward reaction (endothermic) or the reverse reaction (exothermic). When the temperature increases, the equilibrium will shift towards the endothermic direction to absorb the excess heat. Conversely, when the temperature decreases, the equilibrium will shift towards the exothermic direction to release heat.
