Question

Cite examples how change in temperature affect food and medicine

Answer 1

Answer:

Bacteria grow most rapidly in the range of temperatures between 40 and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” That's why perishable foods should never be left out of refrigeration over two hours.

Answer 2

Changes in temperature reduce the action of medicines and can spoil food.

Effect of temperature on medicines:

• Medicines are made of minerals, vitamins, chemicals, and good bacteria.
• All these components have a structure that gets destroyed at lower or higher temperatures.
• Some bacteria may even get killed at high temperatures.

Effect of temperature on food:

• Microbes start growing in food at room temperature. Low temperatures can be useful in preserving food.
• Pasteurization, freezing, and refrigeration are a few preservative methods based on the effect of temperature on food.
• Heat can spoil oil and other fat-based food and make them rancid.
