Frozen soda will not melt faster than ice. In fact, it will typically take longer for frozen soda to melt compared to ice. This is because soda contains sugar and other additives which act as impurities and interfere with the freezing process. As a result, the freezing point of soda is lower than that of pure water, and it requires more energy to melt. Additionally, the sugar in soda can form a syrup that acts as an insulating layer, slowing down the melting process even further.
