What makes molocues spread?
heat which makes it move faster.
Why is vertical flame spread more rapid than horizontal flame spread?
The heat from a fire in the vertical spread is traveling upward and preheating the fuel about to be burned; whereas in horizontal spread, most of the convective heat is escaping into the atmosphere. Only the radiant heat is warming the material to the side.
What do heat particles do?
there is no such thing as heat particles. Electrons carry heat to and from molecules.
What produces heat and destroys pathogens?
liver
How do pathogens survive outside the host?
Many pathogens outside the body can be killed with heat or chemicals. Inside the body, pathogens can sometimes be killed with medicine.
How heat would change the density of a parcel of air?
An increase in heat would cause the air molecules in the parcel to move faster and spread out, resulting in a decrease in density. Conversely, a decrease in heat would cause the molecules to move slower and come closer together, increasing the density of the air parcel.
What happens to the volume of an object when exposed to heat?
When exposed to heat, the molecules of an object begin to move faster and spread out, causing the object to expand. This expansion leads to an increase in volume of the object.
What is the heat process which reduces pathogens to a safe level?
sterilization
How does heat expand a glass?
When heat is applied to glass, the glass absorbs the heat energy causing its molecules to move faster and spread apart. This increase in molecular motion results in the expansion of the glass material, causing it to expand in all directions.
What happens when a balloon is exposed to heat?
When a balloon is exposed to heat, the air molecules inside the balloon start to move faster and spread out, causing the balloon to expand. If the heat is too intense, the balloon may burst due to the increased pressure inside.
Does aroma travel faster in cold or hot air?
Aroma molecules travel faster in hot air because the heat causes the molecules to move more rapidly and spread out faster. In cold air, the molecules move slower and spread more slowly, resulting in a slower dispersion of the aroma.
Does water gain heat or lose heat faster than h20?
land loses heat faster than H20
