The physical state that best describes the scientist's sample is solid (option C).
<h3>What are the states of matter?</h3>
Matter refers to any substance that has mass and occupies space. The states of matter are as follows;
- Solids; a substance in the fundamental state of matter that retains its size and shape without need of a container.
- Gases; a matter in a state intermediate between liquid and plasma that can be contained only if it is fully surrounded by a solid
- Liquids; substance that is flowing such as water; Liquids readily change their relative position, and which therefore retains no definite shape, except that determined by the containing receptacle.
According to this question, a scientist observed a sample of an unknown material to have molecules that are packed closely together and have fixed positions in space relative to each other. It has resistance to deformation and change of volume.
This description best fits the solid state of matter.

Explanation:
As it is given that stream A is super heated. From stream tables, we get that specific enthalpy, (
) is 3054.29 kJ/kg.
For stream B, it is saturated water at 25 degree celsius. It's 
is 2546.54 kJ/kg.
Stream C, data will be as follows.
P = 200 kPa, 
= 0.9
So, 
= 
= 504.47 + 0.9 \times 2201.7
= 2486 kJ/kg
Now, energy balance formula will be as follows.
= 
= 
= 28.16 kg/s
Hence, inflow of saturated liquid is 28.16 kg/s. According to steam table, temperature of wet steam is 
Mass flow rate of out flow is 31.16 kg/s.

0.6 mol / L is the molarity of a solution prepared by dissolving 36. 0 g of NaOH in enough water to make 1. 50 l of solution.
The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another term for molarity.
The ratio employed to indicate the solution's concentration is called its molarity. Understanding a solution's molarity is important since it allows you to determine the actual concentration as well as whether the solution is diluted or concentrated.
Amount of NaOH = 36. 0 g
Amount of water = 1. 50 L
1 mol of NaOH = 40 g,
Moles of NaOH = 36. 0 / 40 g = 0.9 mol NaOH
Molarity of a solution = moles of solute / Liters of solution
Molarity of a solution = 0.9 / 1.50
Molarity of a solution = 0.6 mol / L
