The solubility is greatly impacted by the temperature so for the first one, you say you got a sample at 32 C and you took it to a temperature of 20 C and you got a precipitation, it is easir to dilute a solute with a higher temperature
The sample 2 is at 42C and you will take it to a temperature of 20 C, originally the sample is hotter than the first sample so you can be sure that you will get a precipitate in a bigger ammount so
A bigger mass of NaCl precipitate will form in sample 2
For the second question
It is similar to the first one but here you are taking a "cold" sample at 8C to 20C , there is an increase of temperature, the sample will get hotter and solubility will increase so the answer is
no precipitate will form for sample 2
