What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
Does gas always indicate a chemical change?
No, the presence of gas does not always indicate a chemical change. Gas can form due to physical processes such as evaporation or changes in temperature, without any chemical reactions taking place.
The precipitation of a solid can indicate a?
chemical reaction taking place, a change in temperature or pressure, or the formation of a new phase in a solution. It can also be used as a method for separating components in a mixture or as a way to purify a solution.
Is this true or false a change in temperature is always an indicator of a chemical reaction?
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.
Is it a chemical change physical change chemical property or physical property when hydrogen chloride is a gas at room temperature.?
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Is a change in the temperature a physical change?
Yes, a change in temperature is a physical change because it only affects the state or phase of a substance (solid, liquid, gas) without altering its chemical composition. It does not result in the formation of a new substance.
Is hot and cold a physical change?
Temperature is a physical phenomenon Change of temperature is a physical change.
What change in a physical property of matter indicate?
a physical change or a chemical change
What would this physical change most likely indicate about changes in the status of the pond?
A decrease in temperature has moved the algae into the stream.
What change in a physical property of matter can indicate?
A change in a physical property of matter can indicate a physical change, such as a change in state (solid to liquid), color, shape, or texture. These changes do not alter the chemical composition of the substance.
How does temperature affect physical and chemical chemical change?
A change in temperature can change the rate of physical or chemical change.
How does temperature change during change of physical change?
Temperature remains constant during the change in phase (physical state).
Does gas always indicate a chemical change?
No, the presence of gas does not always indicate a chemical change. Gas can form due to physical processes such as evaporation or changes in temperature, without any chemical reactions taking place.
The precipitation of a solid can indicate a?
chemical reaction taking place, a change in temperature or pressure, or the formation of a new phase in a solution. It can also be used as a method for separating components in a mixture or as a way to purify a solution.
