Answer:
Explanation:
We usually approximate the density of water to about 
at room temperature. In terms of the precise density of water, this is not the case, however, as density is temperature-dependent.
The density of water decreases with an increase in temperature after the peak point of its density. The same trend might be spotted if the temperature of water is decreased from the peak point.
This peak point at which the density of water has the greatest value is usually approximated to about 
. For your information, I'm attaching the graph illustrating the function of the density of water against temperature where you could clearly indicate the maximum point.
To a higher precision, the density of water has a maximum value at , and the density at this point is exactly .
Answer:
Stars are made of very hot gas. This gas is mostly hydrogen and helium, which are the two lightest elements. Stars shine by burning hydrogen into helium in their cores, and later in their lives create heavier elements.Stars are huge celestial bodies made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores.

Answer:
107.8682 u
Explanation:
Well Silver has an atomic mass of aproximately 107.9. 1 mole of silver atoms = 107.9g and there are 6.02x10^23 atoms in one mole. Therefore to find mass of one atom you should divide the mass by Avodgadro's constant to find the mass of one atom because they all have an even distribution of mass.
The average atomic mass of the element takes the variations of the number of neutrons into account, and tells you the average mass per atom in a typical sample of that element. For example, the element silver (Ag) has two naturally occurring isotopes: Ag-107 and Ag-109 (or 107Ag and 109Ag).
Answer:
they condensate
Explanation:
for the example let's use water vapor when gas particles are cooled down they slow done and then they change the state of matter in this case it turns into a liquid hope this helps
