Answer:
The answer to the 2nd question is C.giants.
Explanation:
Answer:
ΔH vaporization of chloroform is 30.1kJ/mol
Explanation:
It is possible to find ΔH of vaporization of certain compound knowing vapor pressure under 2 different absolute temperatures (In Kelvin) by using Clausius-Clapeyron equation:
<em>Where P is vapor pressure. R is gas constant (8.314J/molK) and T absolute temperature of 1, first state and 2, final state.</em>
Absolute temperatures in the problem are:
T₁ = 24.1°C + 273.15 = 297.25K
T₂ = -6.3°C + 273.15 = 266.85K
Replacing:
30073J/mol = 30.1kJ/mol = ΔHVap
<h3>ΔH vaporization of chloroform is 30.1kJ/mol</h3>
Answer:
Potential energy is the latent energy in an object at rest, and is one of two forms of energy. The other form, kinetic energy, is the energy expressed by an object in motion.
Answer:
Energy is neither created nor destroyed.
Explanation:
The law of conservation of energy states that energy can neither be created nor be destroyed. The total energy of an isolated system remains conserved. It never gets 0. It changes from one form of energy to other but never vanishes.
Hence, the correct option is (d) "Energy is neither created nor destroyed"
