Ice remains at zero degrees C for a long time because all of the heat energy that enters the ice goes into MELTING it, and not into increasing the temperature. Once all the ice is melted, then any more heat energy that enters the system will begin to raise the temperature.
The ice will remain as long as the system remains isolated and the ambient temperature remains above 0 degrees Celsius. If heat is introduced from the surroundings, the ice will start to melt and eventually reach equilibrium by forming a mixture of water and ice at 0 degrees Celsius.
During the course of change of state heat energy given or taken from does not appear as a rise in temperature or fall in temperature of the substance; it is hidden in that substance and is called latent heat and is utilized to produce the change of state. Here mixture water and ice remains at zero degree Celsius, heat energy required to melt the ice is taken from water until it's temperature falls to zero degree.Thereafter the heat energy received is utilized by the ice until it is fully melted.During that time the temperature remains steady at zero degree celsius.When all the ice is converted into water the temperature gradually rises.
It depends ice stroms could be for a long time or they could be for a short amount of time
20 min
Seriously? You are trying to compare a liquid and a solid here. 32 degree vodka will not stay cold as long as ice because vodka will not freeze at 32 degrees.
The time it takes for a cube of ice to melt in 91-degree weather can vary based on factors like the size of the ice cube, humidity, and airflow. Generally, a standard ice cube may take anywhere from 20 to 30 minutes to melt completely in such conditions. However, direct sunlight and wind can accelerate the melting process.
I think its because of pressure on the ice
He was frozen in ice for a long long time.
Ice wont melt at temperatures colder than freezing. Any degree above that will make the ice melt exponentially faster. For example: At 35 degrees, ice will remain ice for a long time. At 212 degrees it will disappear rapidly. At 1000 degrees, it will disappear in a puff of water vapor.
Till the time ice melts
Ice itself does not expire, as it is simply frozen water. However, over time, ice can develop freezer burn or absorb odors from the freezer, which can affect its taste and quality. It's best to use ice within a few months for optimal freshness, but it remains safe to consume indefinitely as long as it has been stored properly.
A lake which remains in a liquid form although it is covered with ice is called an ice covered lake.
