Insulating a cold can of soda reduces the heat flow into the can on a hot day as it acts as a barrier to slow down the exchange of heat between the surroundings and the can. This helps to keep the soda colder for a longer period of time.
Insulation reduces the rate at which heat flows into the can, helping to keep the soda cold for longer. This is because the insulation acts as a barrier to slow down the transfer of heat from the external environment to the can. As a result, the soda inside the can stays cooler for a longer period of time.
When a can of soda is insulated, it reduces the heat transfer between the can and its surroundings. This helps in maintaining the temperature of the soda for a longer period, especially on a hot day, by preventing heat from entering the can and warming up the drink. Insulation acts as a barrier that slows down the movement of heat, keeping the soda cooler for a longer time.
To keep a cold soda in summer, start by chilling it in the refrigerator or freezer for a short time before serving. Use an insulated cooler or a thermal cup to maintain its temperature. Adding ice to the container or using ice packs around it can also help keep the soda cold. Finally, limit exposure to heat by keeping it in the shade or a cool area.
When you take a soda out of the fridge, it absorbs the heat from its surroundings, including the moisture in the air. This heat absorption, along with the cold temperature of the fridge, can make the soda feel cold to the touch even though its actual temperature may not have changed significantly.
Putting a soda can in the refrigerator cools it down because the refrigerator is colder than room temperature, so heat transfers from the warmer soda to the colder air inside the fridge, cooling the soda.

The aluminum material of the soda can is a conductor of heat, so it quickly absorbs the cold temperature from the refrigerator. When you touch the soda can, the coldness is transferred to your hand through conduction, making it feel cold to the touch.
When you take a soda can out of the refrigerator, it feels cold because it's at a lower temperature than your hand. As the can's surface comes in contact with your warmer skin, heat from your hand is transferred to the can through conduction, making it feel cold to the touch.
Baking soda and vinegar gets cold in a reaction called an endothermic reaction. Ectothermic reactions get warm, endo cold. All the heat is taken in by the baking soda and used as energy. If you add more baking soda, more baking soda will take in energy and make it colder. Source(s): Fith Grade science project done in Los Gatos, CA
