Which of the following statements is false? A)
Concentration is the number of particles in a given unit of volume.
B)
Viscosity lets a water strider(insect) walk on the calm surface of a pond.
C)
Candle wax is an amorphous solid.
D)
A gas is a fluid.

think I already know the answer but just checking

D a gas is a fluid

Explanation:

Because gas is an air , not a fluid

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !
