At room temperature an ice cube...is rapidly melt. It is impossible for the ice to have the room temperature (ca. 20 0C) at normal pressure.
Physical changes are reversible. Water turns into ice cubes at lower temperatures and back to water at room temperature
Hot water would take longer to reach the freezing point than room temperature so hot water would freeze slower than water at room temperature
Depends on the starting temperature of the liquid being frozen, the melting point of the liquid being frozen, and the temperature of the freezer being used to freeze the liquid. Of course it depends upon the temperature of the water being placed in the ice trays, and the temperature of the freezer into which the trays are placed ... but mine, room-temp tap water into a stack of 4 ice trays ... about 10 hours.
The room temperature is...the room temperature !!
I don't know a lot about fluorine but I know that it is a pale yellow gas when at room temperature.
Room temperature
because Germans usually drink their water at room temperature
That entirely depends on quantity, the starting temperature and the density, but an average size wheel should reach room temperature from the refrigerator in around 40 mins.
it would depend on the temperature of the room. at 21*c it would melt in 15minutes
No.
Condensation occurs on the outer surface of the glass when you keep ice cubes in the glass at room temperature or hotter.
Unless it has been heated or cooled recently, it will of course have the same temperature as the air in the room - whatever that is.
Everything that has been in the room for a long enough time to reach thermal equilibrium will be at the same temperature, including wood. So if room temp. is 70 F then the wood is 70 F.
The ice is at a constant temperature of 0°C as it melts. Once it has completely melted, the water's temperature will start to rise to equilibrium with the room.
When allowed to stand for long enough, the final temperature will reach room temperature.
It takes about two hours.
The temperature of the water and the something will reach an equillibrium somewhere between the two and eventually both will reach room temperature. Time depends on the temperature and mass of the something and the temperature and volume of the water.
