Question

Why does warm soda go flat faster than chilled soda?

Answer 1

Warm soda go flat faster than chilled soda because GAS MOLECULES MOVE FASTER IN WARM SODA.

A can of warm soda has a raised temperature. Because of its temperature, the molecules of gas inside the drink will acquire more energy, move faster and escape into the atmosphere at a rapid rate; this will make the soda drink to go flat in a short period of time. In contrast, a chilled soda has a very low temperature, because of the temperature the gas molecules in the drink have little energy and move at a slow rate. Thus is takes times for the chilled soda to return to room temperature.

Answer 2

C) Gas molecules move faster in warm soda. 
The actual reason is; the reason for soda going flat is the loss of carbon dioxide dissolved in it, into the atmosphere. 
At low temperatures, the solubility of gasses in a liquid is higher.
