Answer:
n = 0.594 mol
Explanation:
Parameters of the question.
Heat = 979J
Initial Temperature (T1) = 10.6 C = 283.6 K (converting to Kelvin by adding 273)
FinalTemperature (T2) = 26.4 C = 299.4 K (converting to Kelvin by adding 273)
ΔT = T2 -T1 = 299.4 - 283.6 = 15.8K
Work done (W) = 221 J
number of moles (n) = ?
Formular to be used;
W=PΔV
From ideal gas equation,
PV = nRT
PΔV = nRΔT
where R = gas constant = 8.314 J / mol·K
Sunstituting in the work done equation,
we have W=nRΔT
Making n subject of formular,
n = [8.314 * 15.8]/221
n = 131.36/221
n = 0.594 mol
Answer:
Gases, liquids and solids are all made up of atoms, molecules, and or ions, but the behaviors of these particles differ in the three phases, gases are well separated with no regular arrangement. liquids are close together with no regular arrangement, and solids are tightly packed, usually in a regular pattern.
Answer:
Oxygen exists as a diatomic molecule in nature when it is not combined with any other element. It forms O2 molecule because it is stable when it is uncombined. It has the lowest energy level when uncombined. ... By achieving octet configuration, the diatomic elements become more stable compared to the single atom.

Well, the sun is in space, right? It has to be able to transfer heat through space, or how would it get to us? Radiation helps transfer heat.
