is physical change because it's revers-able. if we turn the temperature full so we also can change this again or turn it off so yah its physical
Temperature change is a physical phrenomenon.
Physical.
Heat absorption is a physical change. It can cause a change in state and/or a temperature increase, but the matter that is absorbing the heat does not change. It retains all of its physical and chemical properties that it had before absorbing the heat.
b) chemical changeyou guys r not smart :)
It is a physical change.
chemical change
It is a chemical change. Actually "Perspiration" is a noun defined as the chemical product produced by sweat glands. sweating is a physical response to increased body temperature. and the reaction to sweating is the physical cooling that takes place when sweat or perspiration evaporates and gives off heat energy.
A change in temperature can change the rate of physical or chemical change.
Temperature change is a physical phrenomenon.
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
A temperature change can be seen both in physical and chemical changes.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
The observation that hydrogen chloride is a gas at room temperature is a PHYSICAL property.
Melting is a physical change; but above a temperature the thermal decomposition of butter begin - this is a chemical change.
Physical Change
Physical. The mercury doesn't change.
A decrease in temperature is a physical change, not chemical.
a chemical change that can be accelerated by limited increased temperature
It is a change of a physical property - for example the variation of temperature.
