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.
I do not know so don't ask this question again
No, hot water does not freeze more quickly than room temperature water. In fact, hot water takes longer to freeze because it has to cool down to the same temperature as room temperature water before it can start freezing.
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.
Room temperature water is water that has been allowed to reach the temperature of the surrounding room, generally around 68-77°F (20-25°C). It is neither hot nor cold, making it comfortable for drinking or cooking.
At room temperature and standard pressure the element Boron is a solid.
Room temperature
because Germans usually drink their water at room temperature
Yes, the number of ice cubes does affect the temperature of water. It does so in two ways. First, the greater the mass of ice cubes in the water, the greater the cooling effect.But even if you have the same mass of ice - in one large cube or lots of small cubes, the water with more cubes will cool quicker. This is because there is a greater surface area. Although this will make no difference in the long term in a perfectly insulated container, in normal circumstances, there will be some heat gained through the surroundings and so there will be a tendency towards the ambient temperature. So the shorter term effect does matter.
it would depend on the temperature of the room. at 21*c it would melt in 15minutes
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.
The time it takes for 2 gallons of water to reach room temperature will depend on the initial temperature of the water, the room temperature, and the surrounding conditions. In a typical room environment, it may take a few hours for 2 gallons of water to reach room temperature if starting from a colder temperature.
No.
Condensation occurs on the outer surface of the glass when you keep ice cubes in the glass at room temperature or hotter.
It typically takes about 30-45 minutes for a cup of ice to melt at room temperature. This can vary depending on the temperature of the room and the size of the ice cubes.
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.
A hypothesis for ice cubes could be: If ice cubes are placed in warm water, then they will melt faster than if they are left at room temperature, because warmer temperatures increase the rate of melting in ice.
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.
