In heating frozen foods in sealed pouches in a microwaves, why do you first poke holes in the pouch? A. To prevent the steam pressure from bursting open the pouch B. To allow the heat to get into the food through the hole C. To allow the microwaves to get into the food through the holes D. To allow the aroma of the food to come out through the holes

The correct answer is A. To prevent the steam pressure from bursting open the pouch.

When you heat food in a microwave, the

water molecules in the food vibrate and heat up. This causes the food to cook. However, if the food is sealed in a pouch, the steam that is created by the heating process can build up and cause the pouch to burst. Poking holes in the pouch allows the steam to escape, preventing the pouch from bursting.

Option B is incorrect because the heat from the microwaves will already be able to get into the food through the holes in the pouch. Option C is incorrect because microwaves do not travel through holes. Option D is incorrect because the aroma of the food will already be able to escape through the holes in the pouch.
