Want this question answered?
it depends how cold it is
It should be a cold temperature.
Use a thermometer. =====================
temperature
if the water temperature is too hot it will burn the scalp, if the water temperature is too cold it will not clean the scalp.
The glow stick in the cold water will not glow as bright as the glow stick in the hot water because when you cool the glow stick down, the chemical process will slow down. The glow stick in the hot water will glow brighter but for a shorter period of time.
If you stick a thermometer under the running water, you will see for yourself. Otherwise, you could use a temperature laser gun.
If the temperature is cold then the luminol will have a brighter excited state than if the temperature was hot or room temp.
Ice is cold, right? So the term 'ice cold water' is just comparing the temperature of the water to the temperature of the ice.
cold water absorbs heat from the surroundings and revert to room temperature
Fish are cold blooded. so all you have to do is stick the therrmometer inthe water it is cept in.
it depends how cold it is
Cold water would freeze the fastest because freezing is a physical change brought on by temperature change, and the temperature of cold water is closer to freezing temperature than boiling or room temperature water. Therefore, it would take less time to reach freezing temperature.
it makes warmth
it changes the temp. by the temperature outside,like if its cold out the water will be cold and if it's hot outside than the water will be hot
Stick it in cold water.
It depends on the temperature of the water.
