No.
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
Not necessarily. Things sometimes change colors during a chemical reaction, but a color change is not sufficient evidence of a chemical reaction. You can add drink mix to water and the water turns colors, but it is not a chemical reaction, just a mixture.
A temperature change can be seen both in physical and chemical changes.
False. A change in temperature can indicate a chemical reaction, but it is not always the case. Temperature changes can also result from physical changes, such as phase transitions (e.g., melting or boiling). Therefore, while temperature change can be a sign of a chemical reaction, it is not a definitive indicator on its own.
Pressure Temperature Changes in the molecular structure(chemical change)
Yes, a temperature change without a chemical change is possible. A piece of ice can melt into water and then evaporate into water vapor. These changes are all physical changes, and there must be a change in temperature for them to occur.
A chemical change produces a form of matter that was not there before. Evidence of a chemical change could be changes in temperature, color, smell, and the production of a gas or a precipitate.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Oxygen is a chemical element, so its presence does not involve a chemical change. It undergoes physical changes such as changes in state (gas to liquid) based on temperature and pressure.
They have excellent chemical high resistance. They also have better resistance to temperature changes.
They have excellent chemical high resistance. They also have better resistance to temperature changes.
A change in state does not necessarily indicate a chemical change. Melting, freezing, boiling, or condensing of a substance are physical changes that do not involve a change in the chemical composition of the substance.
