This table has the solubilities of many substances ranging from 0C to 100C:
334.8 Joules
The temperature of the glass become also 10 0C.
Short answer: 2kcalTo be preceise, it depends on the temperature of the water, because the heat capacity of a substance changes with temperature. But in a practical sense, that doesn't matter, because the change is usually very small.If we know the definition of a calorie, it's actually quite easy to calculate this. 1 calorie is the amount of energy required to increase the temperature of 1g of water by 1C. What we need to do is just play with the definition so that it fits with our numbers. So to raise 100g of water with 20C, we need 1cal*C-1*g-1*100g*20C = 2000 cal = 2 kcal (1 kcal = 1 kilocalorie = 1000 cal)
Aniline (phenylamine) is only slightly soluble in water (3.6g/mL @ 20C). This is a volatile amine. It would be similar to trying to mix benzene with water, or any other typical household solvent/degreaser with water. You would see a separation of the liquids into layers.
To raise the temperature of water in a thimble of water from 0 to 100 requires a small amount of thermal energy. To do the same with a swimming pool would require putting a huge amount of thermal energy into the water comparatively speaking.
Yes. It has a solubility of about 91g/100mL of water at 20C.

-20F is colder than -20C. This is because the Fahrenheit scale has a smaller degree interval than the Celsius scale, so -20F is a lower temperature than -20C.
Yes, salts with alkali metals and bromide are soluble.

The two unidentified solids are likely different substances because they have different solubilities in water at the same temperature. Solubility is a characteristic property of a substance that depends on its chemical composition. If two substances have different solubilities, they are likely made up of different molecules or ions.
