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 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.
When does the color change in a leaf indicate physical change and when dos it indicate chemical change?
The color change in a leaf typically indicates a chemical change when it results from the breakdown of chlorophyll and the revealing of other pigments, such as carotenoids and anthocyanins, as the plant prepares for winter. This process involves biochemical reactions that alter the pigments present in the leaf. Conversely, a physical change may be indicated if the color change is due to external factors like exposure to light or temperature without altering the leaf's chemical composition.
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.
