Is water absorbing in a sponge a physical change?
Yes, water being absorbed into a sponge is a physical change because the water molecules are simply being taken up into the empty spaces within the sponge's structure. The water molecules do not undergo a chemical reaction that would alter their chemical composition.
What does exposed persons mean?
"Exposed persons" generally refers to individuals who have come into contact with a source of potential harm or danger, such as a contagious virus, hazardous substance, or a risky situation. These individuals may be at increased risk of negative consequences and may require monitoring, support, or intervention to minimize harm.
What is the change in molecular movement when water evaporates?
When water evaporates, the molecules gain enough energy to break free from the liquid phase and enter the gas phase. This results in an increase in the overall movement of water molecules as they transition from being closely packed in the liquid to being more spread out in the gas phase.
Is copper turning green when exposed to the environment a chemical change?
Chemical because it is being exposed to another compound and forming a new substance
Why does air cool more slowly after it reaches dew point?
When air evaporates it absorbs the heat of evaporation of water from the air, thus cooling it. When the air is at or below the dew point temperature, water no longer freely evaporates from it; thus this heat is no longer being absorbed from the air.
When the forehead of a person is being sponge with colonge he feels refreshedwhy?
Cologne (and alcohol in general) has a low vapor pressure, meaning that it evaporates easily. When it evaporates, it absorbs heat energy from its surroundings (in this case, your forehead), which cools you down.

Why can a sponge return to its original shape after it is being compressed without referring to to its material being flexible?
A sponge can return to its original shape after being compressed because of the air pockets present within its structure. When pressure is applied, these air pockets collapse temporarily, but once the pressure is released, the air flows back into these pockets, causing the sponge to expand back to its original shape.
How water changes from gas to liquid?
When the liquid is exposed to extreme heats, it evaporates, forming a gas. This is because of the particles shrinking and being able to move around more freely. If it is exposed to cold temperatures, the particles enlarge, so that there is not much room for movement, causing a solid object.
What animal can survive most without water?
The Tardigrades can live for a decade without water, being frozen or boiled, float in space, exposed to radiation, and live for 200 years.
What material that has been tested to ignite without an external ignition source within five minutes of being exposed to air?
Spontaneously Combustible
Will being exposed to 200 degrees burn you?
Yes, being exposed to 200 degrees can cause burns on your skin.
What is a homophone and synonym for unclothed and uncovered?
A homophone for "unclothed" and "uncovered" is "bare," which refers to being exposed or without covering. A synonym for both words is "naked," meaning without clothing or covering.
Can oil float on a sponge?
Yes, oil can float on a sponge, as sponges are typically made of porous materials that can absorb liquids. However, the oil will not be absorbed in the same way that water would be, due to oil's lower density and different chemical properties. Instead, the oil may rest on the surface of the sponge or fill its pores without being fully absorbed. The effectiveness of this process depends on the sponge's material and the type of oil.
If an animal by definition has to move how can a sponge be an animal and not move?
The definition of animals only says that most have independent motion. Stationary animals (sponge, coral, anemones, and some mollusks) get food without moving around.Animals are differentated from plants by structure and being exclusively heterotrophs, or consumers.
What are some of the jobs in Greece?
My friend's great grandfather was a sponge diver and sponge merchant. WE CHANGED THE ANSWER BECAUSE Imtheman123 WAS BEING RUDE
Is sponge an elastic material?
No, sponge is not considered an elastic material. Elastic materials have the ability to return to their original shape after being stretched or compressed, while sponge will deform and retain its new shape.
