Does bad bacteria grow on food if put in refrigerator hot?

Yes, it does. When food is hot, it is at a higher temperature, and bacteria grow faster at higher temperatures. This is why it is important to let food cool down before refrigerating it. If you put hot food in the refrigerator, the temperature inside the refrigerator will rise, which can cause other food in the refrigerator to spoil more quickly. Additionally, the hot food can release steam and moisture into the air in the refrigerator, which can create an environment that is more conducive to bacterial growth.
