Its not exactly the metal but the metallic salt in general. in general chemistry, the van't hoff factor for that compound will affect the rate at which the melting point of the ice will decrease. the salts, such as calcium chloride, lower the melting point of ice by a certain degree related to its specific van't hoff factor. usually, a common trick is to use the number of atoms involved in the salt to approximate its factor. For example, calcium chloride, or CaCl2, has three atoms in it. So its factor is about three. This is all related to freezing point depression (courtesy of wikipedia):
ΔTf = Kf · mB where * ΔTf, the freezing point depression, is defined as Tf (pure solvent) − Tf (solution), the difference between the freezing point of the pure solvent and the solution. It is defined to assume positive values when the freezing point depression takes place. * Kf, the cryoscopic constant, which is dependent on the properties of the solvent. It can be calculated as Kf = RTm2M/ΔHf, where R is the gas constant, Tm is the melting point of the pure solvent in kelvin, M is the molar mass of the solvent, and ΔHf is the heat of fusion per mole of the solvent. * mB is the molality of the solution, calculated by taking dissociation into account since the freezing point depression is a colligative property, dependent on the number of particles in solution. This is most easily done by using the van 't Hoff factor i as mB = msolute · i. The factor i accounts for the number of individual particles (typically ions) formed by a compound in solution.

Ice in a metal gauge does not melt primarily due to the thermal conductivity of the metal. Metals conduct heat efficiently, allowing them to quickly transfer heat away from the ice, maintaining a temperature that prevents melting. Additionally, if the gauge is exposed to cold temperatures, the surrounding environment can further inhibit the melting process. As a result, the ice remains solid despite being in contact with the metal.
The material of the container affects the rate at which heat is transferred to the ice. Materials with higher thermal conductivity, like metal, will melt the ice faster as they transfer heat more efficiently than materials with lower thermal conductivity, like plastic or Styrofoam. So, a metal container will lead to faster melting of ice compared to a plastic or foam container.
Salt lowers the freezing point of water, causing ice to melt faster when salt is added. On the other hand, sugar does not affect the freezing point of water, so it does not have a significant impact on the melting rate of ice. Higher concentrations of salt will result in faster melting of ice compared to lower concentrations.
Well, isn't that a fascinating question! You see, the shape of ice can indeed affect the melting rate. A larger surface area means more contact with the surrounding temperature, causing the ice to melt faster. So, if you're ever experimenting with ice shapes, remember to observe how they melt in different ways. Happy exploring, my friend!
Adding salt to melting ice lowers the freezing point of water, causing the ice to melt at a lower temperature. This results in faster melting of the ice.
Yes, shape simply affect of its melting. Affecting its melting's just the law of the land
Yes
If the container is cold, then the ice cream will stay colder longer, therefore taking less time to melt. If the container is warm, the ice cream will get slightly warmer than if it was cold, which makes it take less time to melt.
yes it can because it is a spice
The polar ice melt is affecting the melting rate of ice as it is rising the level of the seawater which may lead to submergence of land.
the hotter the water the faster the ice will melt
Garlic does not affect the melting point of ice. The melting point of ice is primarily determined by the temperature of its surroundings and the amount of energy present to break the hydrogen bonds holding the ice together. Garlic does not play a role in this process.

The independent variables in an ice melting experiment could include factors that might affect the rate of ice melting, such as temperature, surface area of the ice cube, presence of salt or other substances on the ice, or the ambient humidity. These are variables that can be manipulated by the researcher to observe their impact on the melting process.
Yes
Yes, different containers can affect the speed at which an ice cube melts. For example, a metal container will conduct heat more quickly than a plastic container, resulting in faster melting. Additionally, a container with a larger surface area exposed to the surrounding temperature will also lead to faster melting.
