If a section of a lung is cut from a fetal pig and dropped in a glass of water it will sink as it contains no air. Give an explanation why the lung of a fetal pig would not contain air.?
The lungs of a fetal pig do not contain air because a developing fetus receives oxygen and nutrients from the mother's bloodstream through the placenta, not from breathing air. Therefore, there is no need for the lungs to be inflated with air until birth when the piglet starts breathing independently.
Will scoria float or sink in water?
Scoria is a type of volcanic rock that is typically denser than water, so it will sink in water.
Is distilled water sink water?
no
Is tap water from the sink different from the tap water from the fridge?
If the refrigerator water is filtered, then it would be different from the tap water coming from the sink.
What can sink in water?
Objects that are denser than water can sink, such as rocks, metal, or certain types of wood. Additionally, some objects that are initially buoyant may sink if they become waterlogged or if their weight increases.
Why will the segment of lung tissue cut from the fetal pig sink when placed in water?
Healthy lung tissue from an adult pig will float in formalin because there is a (relatively) large volume of air trapped in the alveolar sacs. Fetal pigs haven't taken a breath yet, so there is no air in the alveolar sacs. This is why the lung tissue from a fetal pig will sink in formalin. Incidently, this is also how medical examiners can determine if a child was stillborn or was born alive and then died - check to see if a section of lung from autopsy floats in the formalin.
Does the piece of lungs tissue float or sink in water?
Lung tissue is denser than water and will sink when placed in it.
What happens when lungs you put tissue into water does it float or sink?
Lung tissue would typically sink in water because it is denser than water. The air sacs in the lung would collapse and the tissue would be more solid, leading to sinking rather than floating.
Do tissue float?
Tissue does not float in water. Tissue is denser than water, so it will sink when placed in water.

Why does tissue sink when you put it in water?
In a piece of tissue , there are a lot of small spaces if you look closely enough. This spaces allow water to be absorbed hence increasing both the mass and the volume of the tissue. With greater mass and volume , the density of the tissue would be higher compared to the density of the water which is 1g/cm3 . Therefore , causing the tissue to sink in water .
Will a living person sink in water?
It depends, some people are naturally buoyant, others sink. Normally if you have a lung full of air you will naturally float and if you breath out you will sink.
Is tissue paper float?
Yes, tissue paper is lightweight and will typically float in water. However, if the tissue paper becomes saturated with water, it may eventually sink.
Why doesn't tissue float?
tissues don't float because they absoarb water, so they sink.
What happens if a piece of lung is put in water?
It depends if the lung was ever used. In a baby who died before they ever drew their first breath, the lung would sink. Anyone else who have taken at least one breath, their lung would float because one can never fully expel all the air from your lungs no matter how hard you exhale.
How can a sewing needle float on the surface of water?
The needle does not break the surface tension (meniscus). Get a small piece of toilet tissue and lay it on a glass of water. lay a needle on the tissue. The tissue will become sodden and sink, leaving the needle floating on the surface tension. Put the smallest drop of washing-up liquid on the water. The surface tension will be destroyed and the needle will sink. Try it.
What clogs a sink?
