Nigel fills one beaker with cold water and a second beaker with hot water. He adds salt to the beakers and stirs well. He
then observes that salt in hot water dissolves faster.
Which statement could be considered a scientific inference based on his observations?
O Solubility is directly proportional to the temperature of the solvent.
O Solubility does not depend on the temperature of the solvent.
O Solubility is directly proportional to the volume of the solvent.
O Solubility is inversely proportional to the temperature of the solvent.
