Answer:

Water is a polar molecule.

Explanation:

The fundamental rule of solubility is that "like solutes would dissolve in like solvents". Both NaCl and water are polar compounds.

NaCl is an ionic compound which forms from transfer of an electron from the Cl atom and a loss of electron from Na. This leaves a separation of charge on both atoms with Na being positively charged and Cl being negatively charged. This charge separation makes NaCl a polar compound.

Water on the other hand is a polar covalent solvent. The covalent bond results from the sharing of electrons between oxygen and hydrogen atoms. Due to the more electronegative nature of Oxygen, it pulls the shared electron more closely to itself than the Hydrogen atom. This unequal sharing of the electron leaves a net positive charge on Hydrogen and a negative charge on Oxygen.

For this reason, NaCl will dissolve in water.

Viefleur [7K]
According to the Law of Conservation of Energy, energy is neither created nor destroyed. They are just transferred from one system to another. To obey this law, the energy of the substances inside the container must be equal to the substance added to it. The energy is in the form of heat. There can be two types of heat energy: latent heat and sensible heat. Sensible heat is energy added or removed when a substance changes in temperature. Latent heat is the energy added or removed at a constant temperature during a phase change. Since there is no mention of phase change, we assume the heat involved here is sensible heat. The equation for sensible heat is:

H = mCpΔT
where
m is the mass of the substance
Cp is the specific heat of a certain type of material or substance
ΔT is the change in temperature.

So the law of conservation of heat tells that:

Sensible heat of Z + Sensible heat of container = Sensible heat of X

Since we have no idea what these substances are, there is no way of knowing the Cp. We can't proceed with the calculations. So, we can only assume that in the duration of 15 minutes, the whole system achieves equilibrium. Therefore, the equilibrium temperature of the system is equal to 32°C. The answer is C.

Air is cooled in a process with constant pressure of 150 kPa. Before the process begins, air has a specific volume of 0.062 m^3/
Mama L [17]

Answer:

The pressure is constant, and it is P = 150kpa.

the specific volumes are:

initial = 0.062 m^3/kg

final = 0.027 m^3/kg.

Then, the specific work can be written as:

W = \int\limits^{vf}_{vi} {Pdv} \, = P(vf - vi) = 150kPa*(0.0027 - 0.062)m^3/kg = -5.25 kPa*m^3/kg.

The fact that the work is negative, means that we need to apply work to the air in order to compress it.

Now, to write it in more common units we have that:

1 kPa*m^3 = 1000J.

-5.25 kPa*m^3/kg = -5250 J/kg.
