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.
A physical change is reversible and does not affect the composition of a substance. On the other hand, chemical change is irreversible and permanent. A substance undergoing a chemical change forms a new substance which has different composition than the original substance.
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.
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.
A change in temperature can change the rate of physical or chemical change.
Almost all chemical changes release or take in energy, and thus do result in changes in temperature.
No.
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 enthalpy temperature dependence influences the overall energy changes in a chemical reaction by affecting the heat absorbed or released during the reaction. As temperature increases, the enthalpy change also changes, which can impact the reaction's energy balance.
chemical changes affect the chemical properties as well as composition of matter , that result in the formation of a new substance.
A temperature change can be seen both in physical and chemical changes.
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.
