C is the answer I just check it on mine
It's when they take the blood lost In surgery and put it back in the patient
A seismologist would be involved with the study of methods to predict earthquakes.
Condensation is the collection of droplets on a cool surface when humid or warm air is in contact with it. an example would be if you had a glass of ice water, after a while the outside of glass would have water droplets.
a freezing point is the temperature at which a liquid turns into a solid. an example would be if you were to take a glass of water and place it in the freezer overnight it would freeze.
a melting point is the temperature at which a solid will melt. an example of a melting point would be 32 degrees Fahrenheit or 0 degrees Celsius for water.
sublimation is the chemical process of which a solid turns into a gas without going through a liquid stage an example would be when Ice Cubes "shrink" in the freezer.
vaporization is the process when a chemical or element is converted from a liquid or a solid to a gas. for example liquid nitrogen is an inexpensive cryogenic liquid that has a temperature of -190 degrees C, which is very near its boiling point. when exposed to room temperature, the liquid boils, and gives off a invisible nitrogen vapor. if you were to spill some liquid nitrogen on the floor, it would make a puddle, then vanish in a few seconds. Heat from the room and there's a puddle and raises its temperature and causes the liquid to evaporate.
Hope this helps!
The purple color of potassium permanganate gradually spreads throughout the water in the jar by the process of diffusion.
- Diffusion is the process of movement of a substance from the region of higher concentration to the regions of lower concentration. Diffusion occurs in liquids as well as gases.
- Potassium permanganate is a purple color compound, when it is added in a jar of water it spreads throughout the water by the virtue of diffusion.
- The concentration of potassium permanganate is higher at one point and the other regions in the jar have its nil or low concentrations initially, this leads to the set up of a concentration gradient.
- As time passes diffusion occurs and the particles of potassium permanganate keep on migrating to the regions of low concentration until the concentration is uniform throughout the jar. Ultimately, it spread throughout the jar making the water purple.
