The particles in a hot coffee possess greater kinetic energy compare to the particles of an ice cream due to the nature of their states of matter.

Explanation:

The particles of liquid substance are held together by weak intermolecular force of attraction and therefore are far from each other which cause them to be able to move about freely in the hot cup of coffee. Due to easy movement they will have more kinetic energy and move at a faster rate due to application of heat. Due to this heat, the particles in the hot coffee will be free to move about and strikes the wall of the container which in turns increases their kinetic energy since kinetic energy is the energy possessed by a body by virtue of its motion.

An ice cream is a semisolid and in a semisolid compare to liquid substance, the molecules/particles of the substance are held together by intermolecular force of attraction and hence, this particles will not be able to move freely and as such will possess low kinetic energy compare to the particles in the hot coffee.

Answer from: Quest

the arctic is a region of the planet, north of the arctic circle, and includes the arctic ocean, greenland, baffin island, other smaller northern islands, and the far northern parts of europe, russia (siberia), alaska and canada.

Answer from: Quest

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic = - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
