What is the freezing poiint of iodine?
I have looked on many different websites but I believe it to be 236.4 Fahrenheit.
Is the freezing point of water a physical state?
No it is the temperature at which water changes physical state from a liquid to a solid.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation of solid iodine into purple vapor is a physical change because the chemical composition of iodine remains the same throughout the process. Only the physical state changes from solid to gas.
Is freezing point a physical property or physical change?
Freezing point is a physical property. It is the temperature at which a substance changes from a liquid to a solid state under standard atmospheric pressure. Physical changes involve a change in state without altering the chemical composition of a substance.
Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
What is the physical state of iodine when it is at 250 celcius?
Iodine is in gaseous state at 250 degrees Celsius.
What is a physical property that tells you when a liquid would change into a solid?
The melting point is a physical property that indicates when a liquid will change into a solid. It is the specific temperature at which a substance transitions from a liquid state to a solid state.
State two quantitative physical proparties that change when antifreeze is dissolved in water?
It chances the boiling point of the water, and it changes the freezing point of the water
What is the physical state of iodine at 21 degrees?
gas
Is iodine melting a chemical or physical change?
Iodine melting is a physical change, as it does not alter the chemical composition of the iodine. It simply changes from a solid to a liquid state due to the input of heat energy.
What is colour and physical state of iodine?
Iodine is a dark purple or black solid at room temperature.
Is freezing biological samples for storage a chemical or physical change?
It is a physical change. Any change in state or temperature is only physical unless it causes the atoms in the molecules to separate or rearrange themselves. In the case of freezing a biological sample, the point is to preserve it as it is, so the change would only be physical.
