Dishes holding food stay cool in a microwave oven.. _____ 2. Only containers made especially for microwave ovens can be used for cooking in a microwave oven.. _____ 3. Food in a microwave oven cooks very evenly.. Microwave ovens generate electromagnetic waves (called microwaves) which makes water move. This motion leads to friction, and friction leads to heating. Microwave heating works by heating water in foods by making water molecules vibrate. That is why dry foods like . Astronomy 123. Cosmology. Cosmology is the empirical study of the organization, structure and evolution of the Universe. At any given time we always think our Cosmology is correct: . Ancient: Earth is at center of Universe.
