An object will float in a liquid if it is?
a. cooled to the same temperature.
b. heated to the same temperature.
c. less dense than the liquid.
d. more dense than the liquid.

C

Explanation:

For instance, if density of water =1

Plastic ball = 0.78

Ball is less dense than water,hence it will float while if density of plastic ball>1, it is more dense and it would sink

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
