Temperature is a physical phenomenon Change of temperature is a physical change.
A change in temperature can change the rate of physical or chemical change.
Temperature remains constant during the change in phase (physical state).
Some factors are: low temperature, low pressure, low concentration of reactants, no stirring, coarse particles, etc.
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.
No
Temperature change is a physical phrenomenon.
Density and specific internal energy are two physical properties that change with temperaturea change in temperature.
Not necessarily. It does, however, indicate that a reaction is taking place.
It is a change of a physical property - for example the variation of temperature.
A change in the physical environment - a change in temperature or pressure
This is a physical process.
