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:

Answer:
W = -148.8 J
Explanation:
given,
mass = 9.2 kg
initial speed = 1.42 m/s
pulling force = 94 N
angle θ = 19.6°
coefficient of kinetic friction = 0.400
the crate is pulled = 4.92 m
to calculate of work done by the gravitation force
gravitation force
W = ( m g sin θ ) x
W = 9.2 × (-9.8) × sin 19.6° × 4.92
W = -148.8 J
Work done by the gravitation force is taken as negative because gravitation force act opposite to the force applied.
Speed is scalar quantity that is defined only by its magnitude and is represented with one value.
Velocity on the other side is a vector quantity that is defined with its magnitude and direction. The speedometer measures and displays the speed of the vehicle.
Where the needle points on the speedometer that is the speed of the vehicle.
The velocity is not explicitly shown, but if f the needle is moving<span>, you can get a rough idea of acceleration. If the needle is going clockwise the vehicle is accelerating.</span>
