Answer:

Option A an E.

Explanation:

Energy can be described as the capability to do work. It is what has to be transferred to an object in order to get this object to do work. Energy can be in various forms such as heat energy, kinetic, potential, electrical, chemical, nuclear etc.

It takes energy to do quite a number of things, from cooking food to driving and also in engaging in exercises.

Neon is compressed from 100 kPa and 16°C to 500 kPa in an isothermal compressor. Determine the change in the specific volume and
Viktor [21]

Answer:

\Delta v=-0.952m^3/kg

\Delta h=0

Explanation:

In this case, since neon could be considered as an ideal gas, the specific volumes at the first and second state are respectively:

v_1=\frac{Rg*T_1}{p_1}=\frac{0.4119kJ/kg*K*289.15}{100kPa} =1.19m^3/kg\\

v_2=\frac{Rg*T_2}{p_2}=\frac{0.4119kJ/kg*K*289.15}{500kPa} =0.238m^3/kg\\

Thus, the change in the specific volume turns out:

\Delta v=v_2-v_1=0.238m^3/kg-1.19m^3/kg\\\Delta v=-0.952m^3/kg

Which value has sense for the compression.

In addition, the specific enthalpy change just depend on the temperature as it is an ideal gas, therefore, since the process es isothermic:

\Delta h=Cp\Delta T=0

Best regards.

krok68 [10]
I think the correct term to fill in the blank would be equal. According to the law of conservation of mass, when sodium, hydrogen, and oxygen react to form a compound, the mass of the compound is equal the sum of the masses of the individual elements. This particular states that the mass cannot be created nor destroyed. So, for every process, the total inflow of mass should be the same total mass for the outflow since mass should be constant all through out. So, for a reaction, the total mass of the reactants should be equal to the total mass of the products.
