It sounds like you're asking about the difference between an ice cube with pepper in it and an ice cube in the sun. Here's how I understand the question and the differences:

1. The Pepper:

* Flavor: The pepper will add a spicy flavor to the water when the ice cube melts.

* Appearance: The pepper might be visible in the ice cube, creating a visually interesting effect.

2. The Sun:

* Melting: The sun's heat will cause the ice cube to melt faster, regardless of whether there's pepper in it or not.

* Temperature: The ice cube will absorb heat from the sun and its temperature will rise until it melts completely.

So, the key differences are:

* Flavor: An ice cube with pepper will taste spicy, while a plain ice cube will not.

* Melting Rate: Both ice cubes will melt in the sun, but the pepper won't significantly affect the rate at which they melt.
