If we want to know the temperature at which a liquid turns into a solid, we should look for its ___. A. boiling point B. melting point C. freezing point D. heating point 相关知识点: 试题来源: 解析 C。解析:freezing point是冰点,如果我们想知道液体变成固体的温度,就应该查找它的冰点。A...
Most things have three states:solid,liquid and gas.We can change a solid into a liquid and liquid into a gas.It doesn't matter which of the three states a thing is in,it is still the same thing.Let's think about water to see how this works....
1.根据If the temperature falls below zero, liquid water will turn into ice. So the liquid turns into the solid.可知答案。 2.根据When it is a gas, you may not see or feel it.可知答案。 3.根据The heat of the sun turns liquid water into gas from the oceans, seas, rivers and la...
The heat of the sun turns liquid water into gas from the oceans, seas, rivers and lakes. The heat also turns liquid water into gas from the ground, the plants and the animals. Water in the gas rises and turns into clouds in the air. When the clouds come near a mountain, they ri...
Water can exist in three states: solid, liquid, and gas. When water freezes, it turns into ice, which is the solid state. When water boils, it turns into steam, which is the gas state. The process of water changing from a liquid to a gas is called ___. A. evaporation B. condens...
