### Why does more ice melt slower than less ice?

Water has heat of fusion about $H_{fus} =80~\text{cal/g}$, this means that for melting 1 gram of ice you need about 80 calories of heat. Obviously having more ice (monolithic piece or fragmented ...

### Why does more ice melt slower than less ice?

The reason is still basically a variation of the square cube law. A pile or cup of ice cubes have more volume to melt relative to the effective surface area to perform heat transfer compared to if you ...

### Do liquids typically solidify under enough pressure?

The example you have chosen to start your question (water) is an atypical case. The phase diagram has a logarithmic scale for the pressure, somewhat hiding the negative slope of the transition line ...

### Why does more ice melt slower than less ice?

Hey I think the statement: ice cubes that are larger melt slower because of their surface area is not truly correct. you know greater the surface (through which heat transfer occurs) lesser will be ...

### Why do phase changes have to be isothermal processes?

I was wondering why, as the ice melts, why does the temperature not increase as it is changing phase? There are two components of the internal molecular energy of a substance: Kinetic energy and ...

### Steam from a cup of coffee

The amount of water that air can take up before the water creates fog or visible steam depends on temperature. The colder the air, the less water it needs to create fog/steam. It is the same principle ...

### Do liquids typically solidify under enough pressure?

No, there are some substances which never become solids. One example: He. If we have 3He, it will form a Bose-Einstein condensate if I remember correctly.

### Materials known to have higher density than Osmium at at high pressure and/or low temperature

Osmium’s density at 500 Gpa is about 35~36 g/ml according to from dividing the room temp density by the percent volume
