What part of an icecube melts first?

Question

also why do larger ones take longer?

Answer 1

The melting happens at the surface of the ice cube.  Larger cubes take longer to melt because they have a larger volume of ice compared to their surface area.  

Let's look at an example.  An ice cube that is one centimeter on each edge has a volume one cubic centimeter and a surface area of 6 square centimeters.   A second ice cube is 2 centimeters on each edge, so it has a volume of 8 cubic centimeters and a surface area 24 square centimeters.

The first one has a ratio of surface area to volume of 6:1.  The second has a ratio of surface area to volume of  24:8 or, equivalently, 3:1.  This means that the melting at the surface compared to the volume of ice is twice as fast for the smaller cube than it is for the larger cube.  Thus, the smaller cube melts in half the time.

Answer 2

the part you press against her nipple... uh, sorry, wrong group?

Answer 3

the bottom part on which the pressure of its weight acts the most.

Larger ones take longer cause it has more ice to melt.

Answer 4

The outside. That also explains why larger ones take longer. There is a lot more volume to the large icecube but only a little more surface area. Imagine two icecubes, one 1" on a side and one 2". The volume of the first is one cubic inch; its surface area is six square inches. The volume of the second is six cubic inches; its surface area is 24 square inches. The ratio of volumes is 1:6 but the ratio of surface areas is only 6:24 or 1:4. There is relatively less surface exposed to the warm air.
