For each example of a phase change, identify whether heat is absorbed from the surroundings or
released into the surroundings.
a popsicle melts on a hot day.
rubbing alcohol evaporates from the surface of the skin.
lava solidifies when it erupts from a volcano.

Answers

Freezing ice cream is the correct answer.

Cooking a pot of soup

Explanation:

id say that because when you freeze ice cream, its already frozen, so no heat is being released. melting ice wouldn't be the answer because, once again, it is already frozen, and no heat is being released.

B is the answer!! hope it helps

An endothermic phase change would be vaporization. I say this because endothermic changes absorb heat or energy. When something vaporizes it is because it was boiled or evaporated, which contains absorbing heat.

An exothermic phase change would be freezing. Exothermic changes release heat or energy from its surroundings and when something is frozen, it does not contain heat, it releases its heat.

Hope this helps :)

1. Solid to liquid:ice cube melting into water.

2. Liquid to gas:water boiling

3. Solid to gas:dry Ice transfer into carbon dioxide directly.

Explanation:

The term phase transition (or phase change) is most commonly used to describe transitions between solid, liquid, and gaseous states of matter, as well as plasma in rare cases.

Ice melting into water is an example. Or iron melting into liquid iron.

"When water vapor in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That's condensation!" -wonderopolis.org

In case of popsicle and alcohol, heat is absorbed from the surrounding.

In case of lava heat is emitted into the surrounding.

Explanation:

Melting of popsicle is just a change of state from solid to liquid. This is the phenomenon which occurs when the popsicle gets the heat from the surrounding and it absorbs the heat, thereby turning into liquid. So it absorbs heat from the surrounding.

The alcohol when spread on the skin evaporates into vapour. This is the phenomenon of evaporation which occurs when alcohol absorbs heat from the surrounding and thereby turning into vapour.

Similarly, when lava solidifies into solid, the change of state occurs. As lava emits heat into the surrounding, the temperature of the lava goes down, thereby changing it into solid. So it emits heat into surrounding.
