Melting icecream.reversible or irreversible

Melting ice cream is a reversible reaction. A reversible reaction can be undone to get the original product. This is true for melting ice cream as you can freeze the ice cream to get it back to its original state.

Hello

Tundras are among Earth's coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy and rainfall is scant. Tundra lands are snow-covered for much of the year, until summer brings a burst of wildflowers.

If you don't believe me you can look up the question and it will show the same info. This is what the website is
