The temperature change is needed to calculate the enthalpy 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.
.... by measurement with an device designed for one particular property: balance for mass, thermometer for temperature, ruler for length, spectrophotometer for color, photometer for light, etc.
A thermometer can help you decide whether your observation is a physical or chemical change by measuring the temperature change. A physical change typically involves a change in state (solid, liquid, gas) without changing the chemical composition, so the temperature may remain constant. In contrast, a chemical change usually involves the breaking and forming of chemical bonds, which can result in a temperature change.
Well a Chemical change means that what ever changes can't change back. For example if u have normal paper then burn it that's a chemical change and that's why a chemical change is so important.
Oxidation typically involves a chemical change where a substance loses electrons. While you might observe physical changes associated with oxidation, such as a change in color or texture of the material, the process itself is primarily a chemical change.
Yes, temperature have generally an important effect.
A change in temperature can change the rate of physical or chemical change.
you can observe chemical reactions from its smell, colour, shape, or the change in it's properties
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.
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.
The formation of a new substance is the criterion for a chemical change. You can't have a chemical change without the formation of at least one new substance. As you can't observe a chemical property without setting a chemical change in motion, the answer to your question is yes.
gas
Yes. If you observe a chemical property, the substance will be undergoing a chemical change, which by definition produces a new substance.
