Does the type of liquid in a container affect the sound it produces?
example like milk, water and coffee produce a minute different sound

The denser the liquid, the easier the sound will be able to travel through it, making it louder than if the liquid were less dense. Whole cow milk has a density of about 1.03, water 1.00, and coffee is most likely in-between water and milk. This means that if a sound of the same amplitude (loudness) is played through each, you will hear them with in this decreasing order of amplitude: milk, coffee, and then water, which is the quietest.
