Apiece of glass is immersed in a liquid. it proceeds to float on the liquid's surface. this shows that the density of the glass is the density of the liquid.

a. more than
b. less than
c. equal to
d. not comparable

b) Less dense

Explanation:

Differences in density is one reason objects float or sink.

An object more dense than the fluid in which it is immersed will sink, while objects less dense than the fluid in which it is immersed will float to the surface.

But objects floats at constant level if the density is equal to the density of the fluid in which it is immersed; it neither rises nor sinks in the fluid in this case.

*tilts head* sounds more like a statement
