same speed but heat may speed a little bit
Iron has the lowest specific heat, so it will heat up faster.
An ice cube will melt faster in water compared to air due to water's higher thermal conductivity and closer temperature proximity to the ice. In water, the ice cube is able to transfer heat more efficiently, leading to faster melting. In comparison, air provides less efficient heat transfer, causing the ice cube to melt slower.
An ice cube will melt faster in hot water compared to cold water or by itself. The higher temperature of the hot water transfers more heat energy to the ice cube, causing it to melt at a quicker rate.
The melting rate of an ice depends on the temperature of the surrounding. If the temperature is higher in the surrounding then the ice will melt at a faster rate and if the temperature is low then it will take more time to melt. The process of heat exchange is important whether it is air or water.
The ice cube would melt faster in water than in air. This is because water can transfer heat more efficiently due to its higher thermal conductivity, leading to a faster rate of heat transfer from the water to the ice cube, causing it to melt more quickly.
When heat is applied to water, the molecules excite and move faster, and change into a gaseous state.
Ice cube requires heat to melt.Water conducts heat well. Therefore the temperature of the environment is absorbed by the water and the some of the distributed heat is taken by the cube and it melts.Air is an insulator. The only way heat from surroundings can go to the ice cube INSIDE the water bottle is by convection of air currents. But the convection is restricted to some extent by the almost closed water bottle, which has high(compared to cube size) plastic walls (plastic: heat insulator) on all sides and a narrow mouth. Therefore the convection and thus passing of heat to cube from surroundings is slow and this makes the ice melt slower in the empty water bottle.
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.
Heat must have to be applied to the ice cube.
Yes, absolutely. Heat transfer from the surrounding environment into the ice cube causes it to melt. The greater the rate of heat transfer INTO to ice cube, the faster it will melt. The greater the surface area of the ice cube, in relation to it size, the faster the melting will occur. The ideal shape for the least heat transfer [and this is true for cold or hot objects] is a SPHERE. A sphere has the minimum surface area for the mass of the object. Any shape other than a sphere has more surface area for the mass, an will melt faster. The thinner more spreak out ice will melt faster melting consumes enerhy inthe form of heat. The amount of energy needed is the proportional of the ice water. The heat applied to it can be radiation or matter. Johnson Kevin, Ohio
There are many reasons, the one i can think of is its specific heat constant is different.* * * * *Don't know the true answer but the above is not it.
One is the temperature of the water could be warmerSecondly when an ice cube is in water, conduction takes place. The kinetic energy of the water particles more time.moves to the ice causing it to melt. When in air radiation or convection must take place which will take
