Hey there!
In this case, it is possible to solve this problem by using the widely-known steam tables which show that at 90 °C, the pressure that produces a vapor-liquid mixture at equilibrium is about 70.183 kPa (Cengel, Thermodynamics 5th edition).
Moreover, for the calculation of the volume, it is necessary to calculate the volume of the vapor-liquid mixture, given the quality (x) it has:
Thus, since 8 kg correspond to liquid water, 2 kg must correspond to steam, so that the quality turns out:
Now, at this temperature and pressure, the volume of a saturated vapor is 2.3593 m³/kg whereas that of the saturated liquid is 0.001036 m³/kg and therefore, the volume of the mixture is:
This means that the volume of the container will be:

The answer is : B. allow for bonding metals to be stable. Metals, nonmetals all bond to be stable. Metallic bonding is the force of attraction between valence electrons and the metal ions.The electrons and the positive ions in the metal have a strong attractive force between them.
When light strikes a red object, the light waves of all colors except red are <em>absorbed</em> into the object, and never heard from again. <em> (B)</em>
The only thing left to bounce off of the object into anyone's eye is the waves of red.
Atomic mass = number of protons + number of neutrons = 4+5 = 9 amu
Answer:
The focus of Lesson 1 is Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
