What term is used to describe water that is at a desirable temperature and free from objectionable tastes, colors, and turbidity?

The term that describes water which is at a desirable temperature and free from objectionable tastes, colors, and turbidity is "potable." Potable water is safe to drink and meets health standards for consumption. It is important for drinking water to be palatable to ensure that people will consume enough to stay hydrated, and it must also be free from contaminants that could cause illness.

In contrast, the other terms do not accurately describe this quality of water. "Palpable" refers to something that can be felt or touched, which does not pertain to the qualities of water. "Saline" indicates the presence of salt in the water, which is typically not suitable for drinking. "Filtrate" refers to liquid that has passed through a filter, which does not inherently indicate whether the water is safe or desirable for consumption. Hence, "potable" is the most appropriate term for the quality of water described in the question.
