Answer:
(a) Slower the sound travel
Explanation:
The speed of sound also depends on the material it is traveling on. The denser the liquid, the slower the sound can travel and the less denser the liquid, the faster the sound can travel. This is because <u><em>denser materials have larger molecules than less denser materials. </em></u>Sound waves travel through "vibration." It takes more energy to vibrate in denser objects than in less denser ones; thus this explains the<u> slow travel rate of sound in a denser medium of liquid.</u>

<em>Several scientists make the same observations about the effect of sunlight on algae. This set of observation is called Working theory. ... The study of algae is called phycology or algology. The term shields a variety of photosynthetic creatures, and many are not narrowly related.</em>
