Hot water molecules go to wherever pockets of cold are, which would be the room
cold water molecules are moving slowly n stay together
Assume an original volume of blood of one deciliter (100 ml). if 5 ml of oxygen diffuses into the blood, 100 ml will be its final volume.
A tissue is made up of white blood cells, platelets, red blood cells, and other elements suspended in a liquid. Blood transports waste away and delivers nutrients and oxygen to the tissues. The entire amount of fluid moving through the heart's arteries, capillaries, veins, venules, and chambers is referred to as blood volume. Red blood cells (erythrocytes), white blood cells (leukocytes), platelets, and plasma are the elements that give blood volume.
The amount of water and sodium ingested, expelled by the kidneys into the urine, and lost through the digestive system, lungs, and skin determines blood volume. The amounts of salt and water that are consumed and excreted vary greatly.

Answer:
Explanation:
a) chalcogens are elements of group 16 of periodic table.
Tellurium have mass no 125. atomic no 52 so ¹²⁵Te₅₂ is the symbol .
b) halogen ( group 17 elements) radioactive isotope is astatine
atomic no is 85 and mass no may be 210 ( most stable) ²¹⁰At₈₅
c) neon gas is used in lighting .It is a noble gas .
²⁰Ne₁₀ is the symbol
d) lightest alkali metal Beryllium ( Be) .Isotope having 3 neutrons is
⁷Be₄ .
Because white is a color that contrasts heat but black doesn't
