When water ia at around 0-4 degrees, heat(things) shrinks, cold(things) expansions, so when it's around0-4 degrees,surface tension decreases as the temperature increases.When it's above 4 degrees, t...好人做到底...还有这段 温度越高，其具有的热能就越多。速度越快，其具有的动能或动量也越大。能量是可以互相转换的，热能与动能也是可以互相转换的谢谢你。The higher the temperature is，the more the heat it has. The faster it is, thegreater the kinetic energy or momentum it has. Energy can be converted to each other, thermal and kinetic energy can alsobe converted to each other.
