Hello!
We know that by the Law of Avogrado, for each mole of substance we have 6.02 * 10²³ atoms, if:
The molar mass of water (H2O)
H = 2 * (1u) = 2u
O = 1 * (16u) = 16u
---------------------------
The molar mass of H2O = 2 + 16 = 18 g / mol
If:
1 mol we have 6.02 * 10²³ atoms
1 mole of H2O we have 18 g
Then we have:
18 g ------------- 6.02 * 10²³ atoms
5 g -------------- x
I Hope this helps, greetings ... DexteR! =)
Explanation:
The given data is as follows.
P = 3 atm
=
=
= 9 L =
(as 1 L = 0.001
),
= 15 L =
Heat energy = 800 J
As relation between work, pressure and change in volume is as follows.
W =
or, W =
Therefore, putting the given values into the above formula as follows.
W =
=
= 1823.85 Nm
or, = 1823.85 J
As internal energy of the gas is as follows.
= Q - W
= 800 J - 1823.85 J
= -1023.85 J
Thus, we can conclude that the internal energy change of the given gas is -1023.85 J.
Answer:
convection
Explanation:
as air is heated, it rises up and away from the heat source, cools then falls closer to the heat source over and over again.
