1. igloos are buildings that are made of packed
snow. which statement describes the particles
that make up the igloo?

(a) the particles in the snow have no kinetic
energy
(b) the particles in the snow are not attracted to
one another.
(c) the particles in the snow have some kinetic
energy, but the particles only move around in
place.
(d) the particles in the snow melt easily because
they have more kinetic energy than liquid
water.

The particles of the snow have kinetic energy, but being a solid, it has less kinetic energy than that of liquid water. So they move around in a place about its mean position.

Option C

Igloos are the small homes made up of snow. It used to be homes for the people living in Arctic regions in past. Now some tribes still live in these igloos, or they are made by tourists for amusements.

Snow is basically precipitation of ice from clouds. Being the solid form of water, ice has molecules more compactly arranged in its crystal structure. Thus, the molecules cannot move here and there like in fluid. But having some kinetic energy, they have certain movements i.e vibrations around its mean position.

a

explanation:

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
