某实验测量了不同温度下某固体物质的溶解度,数据如下:温度(°C): 10, 20, 30, 40;溶解度(g/100g水): 20, 30, 40, 50。根据这些数据,该物质的溶解度与温度的关系最可能是:
Show the answer and explanation
Correct answer
B. 溶解度随温度升高而增大
Principle or equation
溶解度随温度的变化趋势可以通过数据观察得出。
Why this answer is correct
从数据看,温度从10°C升高到40°C,溶解度从20g增加到50g,因此溶解度随温度升高而增大。
Example
例如,温度每升高10°C,溶解度增加10g,呈线性增长趋势。
