yes
Pepper, on its own, will not melt ice.
Pepper does not melt ice. Pepper is regarded as hot due to its spicy sensation in your mouth when consumed, but it does not have any real heat to it. If you put enough black pepper on ice in sunlight the black pepper will absorb the heat from the sun and may transfer that heat to the ice causing it to melt.
no pepper decreases the melt
You need to determine what you think will melt the fastest, and that will be your hypothesis. If you think that pepper will melt it faster, you would say "My hypothesis is that the pepper will melt ice faster than the other variables (sand, salt, and sugar)."

yes it does, so will salt and probably pepper
Salt
Pepper would only melt ice in the presence of sunlight which would absorb into the pepper, warm up, and raise the temperature of the ice near to or touching the pepper. Coffee grounds, planting soil etc. would work the same way. On a larger size scale, tree trunks often have a hole around them where the snow has melted away, since the bark warms up in even feeble sunlight and radiates the heat into the snow. Salt, on the other hand, combines with the ice (water) to produce a solution with a lower freezing point. This would melt the ice without sunlight, as long as the temperature stays above the new freezing point.
Salt makes ice melt faster than sugar, pepper, or sand. This is because salt lowers the freezing point of water, causing the ice to melt by creating a brine solution that is colder than the surrounding ice. Sugar and pepper will not melt ice as effectively as salt due to their chemical compositions. Sand does not impact the melting rate of ice because it does not lower the freezing point of water.
Salt is the answer to that question. The salt has more chemicals in it that will cause the ice to open up and to melt.
Table salt makes ice melt faster. Salt lowers the freezing point of water, causing ice to melt by dissolving into the liquid water and disrupting the hydrogen bond between water molecules. Sugar, sand, and pepper do not have the same effect on ice melting as salt.
Sugar has a lower freezing point depression than pepper, which means it can lower the freezing point of water more effectively. This allows sugar to dissolve in water and disrupt the hydrogen bonding between water molecules, causing the ice to melt more quickly compared to pepper.
