一、填空题1.一个质量是100克的物体,在0.6牛的阻力作用下,沿竖直方向下落1米,重力对物体做的功等于2.如图1所示,烧杯和小试管中都有清水,用酒精灯对杯底加热,使杯中的水沸腾.用温度计测出烧杯中的水和小试管中的水温度相同.这时小试管中的水将(填“有”?
First, fill in the blank 1. An object with a mass of 100 grams will fall 1 meter in the vertical direction under the effect of resistance of 0.6 N. The work done by gravity on the object is equal to 2. As shown in Figure 1, there are clear water in the beaker and the cuvette, and the bottom of the cup is heated with an alcohol lamp so that the water in the cup boils. Use a thermometer to measure the temperature of the water in the beaker and the temperature of the water in the test tube. At this point the water in the cuvette will (fill in “has”?
