甲、乙、丙三种固体物质(均不含结晶水)的溶解度曲线如图所示。据图回答:

| 温度/℃ | 20 | 30 | 40 | 50 | 60 | 70 | |
| 溶解度/g | KNO3 | 31.6 | 45.8 | 63.9 | 85.5 | x | 138 |
| NaCl | 36.0 | 36.3 | 36.6 | 37.0 | 37.3 | 37.8 | |




| 温度/℃ | 0 | 10 | 20 | 30 | 40 | 50 | 60 | |
| 溶解度/g | M | 27.6 | 31.0 | 34.0 | 37.0 | 40.0 | 42.6 | 45.5 |
| N | 13.3 | 20.9 | 31.6 | 45.8 | 63.9 | 85.5 | 110 | |





| 温度/℃ | 0 | 10 | 20 | 30 | 40 | 60 | 80 |
| 溶解度/g | 7 | 12.5 | 21.5 | 39.7 | 48.8 | 46.4 | 45.8 |



图为甲、乙、丙三种不含结晶水的固体物质的溶解度曲线。| 温度/℃ | 0 | 20 | 40 | 60 | |
| 溶解度/g | KNO3 | 13.3 | 31.6 | 63.9 | 110 |
| Ca(OH)2 | 0.19 | 0.17 | 0.14 | 0.12 | |
