Polar ice is fresh water.
When it floats in the polar sea, it stays ice because the salty sea water can be below 0C. It only melts when the sea water around it gets above 0C.
If that iceberg were in Lake Michigan instead of the sea, it would melt quickly because in order for the lake water to be liquid, it must be above 0C.

Ice melts faster in fresh water, because the salt water is also a preservative that keeps things colder for a longer time.

You use salt to melt ice on a driveway or road, therefore, the assumption here is that salt water would melt ice faster. One generally does not use fresh water to melt ice...

it melts faster in salt water because the presence of salt lowers the freezing point of water, hence less heat is needed to melt the ice. thats why people sprinkle salt onto icy paths/roads.

no, the reason they put salt on ice is because it lowers the freezing point of water. this is because salt water and fresh water have different freezing points. so no, it is not melting faster, it is simply not cold enoguh for it to freeze

ice melts slower in salt water than fresh water. ice water takes longer to freeze. the chemical mixture of h2o and Nacl create the need for colder conditions to freeze and that's why you only see iceburgs in the north and south artic regions. ever made ice cream at home.

when water and salt are combined as a heterogenuis misture, the specific heat of water decreases. thus it uses needs less heat to melt the same amount of water.

i do no longer think of the version must be too super, notwithstanding... An ice cube could drift somewhat greater in salt water than in clean water, particularly because of fact salt water is denser (heavier) than clean water. So greater of the ice would be ABOVE the exterior of the water. If we assume that water is a greater desirable conductor of heat, the greater ice is in touch with the water, the quicker it is going to soften... My superb guess could be that ice lasts longer in salt water. we'd nevertheless ought to look into the warmth conductivity of the two salt and clean water, to boot because of fact the temperature distinction between the air ant the water itself, yet then i'm in simple terms making issues greater perplexing.

fresh water, salt water has a lower freezing temp

I think salt water.
