Why An Ice Melts Faster On Block A

A freezing cold block of aluminium, a room temperature block of plastic, and an ice cube. This is all you need for a simple experiment with a seemingly obvious result. The ice will melt quickly on plastic and stay cold on the aluminium just like it does in a metal water bottle you think to yourself, but the answer is not that transparent. In actuality, the second that the ice hits the aluminium it melts instantly as if it was never a solid to begin with. The ice sits peacefully on the plastic with no change to the state of it. It seems impossible, but there is a very logical explanation to this phenomenon. The ice melts faster on block A (aluminum) because it is a good conductor; the warmth of the aluminum travels to the ice and melts it very quickly (Explanation 3). Although the aluminium is colder than
According to a thermal conductivity chart, the material aluminium has a thermal conductivity of two hundred. This is a higher conductivity than any other materials listed. On the other end of the scale is plastic, coming in at a thermal conductivity of 0.16. This drastic difference proves Explanation 3 true because it states that the high conductivity of the aluminium compared to the plastic is why the ice melts so fast on it. This evidence isn’t so obvious to some, who think that there is a different explanation to the ice melting faster on block a than block b.
Some believe that the ice melts faster on block a because the aluminum absorbs the cold of the ice. According to the Molecular Kinetic Theory of Matter, “The motion of the particles that make up an object decreases when the temperature of an object goes down.” This supports Explanation 1 but it is false. It is a common misconception that the coldness of an ice cube warms up the object, but it is actually the other way around. The warmth of the object, in this case the block of aluminium, transfers to the ice causing it to melt. This is why explanation 1 is
