Is change in size a physical change?
Yes, a change in size is a physical change, as it does not alter the chemical makeup of the substance. Physical changes involve a transformation in the appearance or state of a material without changing its chemical composition.
Would preheating an oven be a physical or chemical change?
Preheating an oven is a physical change because it involves applying heat to raise the temperature of the oven without altering its chemical composition.
If the temperature of heptane increased from 90 degrees to 100 degrees would a physical or chemical change take place?
The temperature increase from 90 to 100 degrees for heptane would not cause a chemical change. It would only result in a physical change, such as a phase change from liquid to gas.
Is freezing point physical property a physical change a chemical property or a chemical change?
The freezing point is a physical property because it describes a characteristic of a substance (temperature at which it freezes) without changing the chemical composition of the substance. When a substance freezes, it undergoes a physical change from a liquid to a solid, not a chemical change.
How can a thermometer be used to help you decide whether your observation is physical or chemical change?
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.
Is hot and cold a physical change?
Temperature is a physical phenomenon Change of temperature is a physical change.
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).
Is temperature a physical change?
No
Is temperature physical weathering or chemical weathering?
Temperature change is a physical phrenomenon.
Is temperature change a physical or chemical change?
Temperature is the perception we have of the vibrational energy of the molecules in any substance. The faster they vibrate, the hotter the object. So the answer is physical.
A change in a physical property of another substance is a one physical change chemical change physical property?
It is a change of a physical property - for example the variation of temperature.
What are the two physical properties that change with temperature?
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
What condition are needed for the physical change to take place?
A change in the physical environment - a change in temperature or pressure
What is classifying a change in temperature?
This is a physical process.
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.
What can be used as an indicator fot a physical change and a chemical change?
A temperature change can be seen both in physical and chemical changes.
