Alist of changes is shown.

temperature decreases
intermolecular bonds become weaker
freezing
intermolecular bonds become stronger
evaporation
temperature increases
vibration of molecules slows down
molecules vibrate faster

which of the above changes would be accompanied by an increase of the kinetic energy of particles in a liquid?

a, b, c, and h
a, c, d, and g
b, e, f, and h
b, c, f, and g

B, E, F, and H

B is true because the bonds are weaker between the molecules when there is a higher kinetic energy

E is true because evaporation is the change of state from a liquid to a gas. particles in a liquid move more slowly in a liquid and in a gas they move quickly. kinetic energy refers to movement so the particles gain kinetic energy when a liquid turns into a gas as theres more movement.

F is true because when the temperature increases, there is more heat energy being transferrer between particles which means they move faster and gain kinetic energy.

H is true because particles only vibrate in a solid (due to fixed positions). in a liquid and gas the particles do not vibrate. so if the vibration decreases, this shows that the particles are becoming more spaced out

The answer is B,E,F and H

Explanation:

If the kinetic energy is increased the temperature can not decrease, nor will the liquid freeze.

passing a magnet thought the

mixture , because iron gets attracted to magnet .

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
