Why does hot/warm water taste different to cold water?!
Answers: because water loses carbon bubbles when it is heated. when u heat a kettle for a cuppa it is best the first time round, i know electricity wise it makes sense to fil the kettle so one boil keeps it warm but every time u boil the kettle u take the goodness out of the water, silly but thats it!!!
Um..... because one is not hot and the other is not cold.
Because its not as refreshing as cold water is, so your body takes it a little differently, hence forth making it seem like it tastes different.
Like any liquid you drink, more compounds can be picked up by tastebuds when room temp or warmer. When hot, you get vapor as well if the liquid is steaming.
hot water has some inpurities boiled out
cos when hot water is biled it loses some of its carbon and oxygen content..
Because hot/warm water has been sitting in the hot water heater for long periods of time. That is why it is always advisable to start all cooking with fresh cold water, rather than water that has been sitting for days in a hot water heater.
Mineral leach? Heat expands, cold contracts. So, hot water picks up minerals from the pipes and pans more readily than does cold.
Also, the sense receptors of the skin, lips, tongue and alimentary canal perhaps open or close accordingly to maintain or release body heat to regulate temperature.
The same liquid can taste differently according to the container it is served in. Wines and liquors can taste different depending on the shape of the glass in which they are served.
I guess it's about presentation, variety, paying attention, and amelioration. :-)
