生活处处是学问,多多观察,你会发现我们身边隐藏着很多科学知识。厨房是我们每天都会去的地方,让我们一起走进厨房,去探探厨房中隐藏着的物理知识吧。厨房中的能量转换进入厨房,首先映入眼帘的便是各种厨具:抽油烟机、煤气灶、电饭锅、砂锅、微波炉等等。抽油烟机把电能转化为机械能,利用空气对流实现空气交换,以吸走厨房里的油烟;煤气灶将化学能转化为内能,通过燃 Life is learning, a lot of observation, you will find that we hide a lot of scientific knowledge around. The kitchen is where we go every day, let’s go into the kitchen together to explore the hidden physical knowledge in the kitchen. Energy conversion in the kitchen Into the kitchen, the first thing that catches your eye is the range of kitchen utensils: range hoods, gas stoves, rice cookers, casseroles, microwave ovens and more. Range hoods convert electrical energy into mechanical energy and use air convection to exchange air to suck the fumes out of the kitchen. Gas stoves convert chemical energy into internal energy,
