Answer:
heating point for water - 100°
Answer:
Horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases.
Step-by-step explanation:
The temperature is constant during a phase change (melting or boiling), so the graph is a horizontal line.
The temperature increases when a single phase (solid, liquid, or gas) is heated, so the graph for these changes has an upward slope.
A is <em>wrong</em>. A horizontal line shows a constant temperature.
B is <em>wrong</em>. There are no vertical lines in a heating curve.
D is <em>wrong.</em> A horizontal line does correspond to an increase in temperature.
Answer:
d. C6H14 > C6H12 > C6H6
Explanation:
Standard molar entropy has to do with the number of atoms that are present in each of the species. The greater the number of atoms possessed by the species, the higher the value of the standard molar entropy due to a greater number of vibration modes.
Hexane (C6H14) has the highest number of atoms followed by cyclohexane (C6H12) and lastly benzene (C6H6).
Thus the order of decreasing molar entropy is; C6H14 > C6H12 > C6H6.
The volume of the Ti unit cell can be calculated using Equation :
For HCP, n tthat is number of atoms/unit cell = 6 atoms/unit cell,
atomic weight for Ti, ATi = 47.9 g/mol.
Thus, 
= 1.058 × 10−22 cm³/unit cell
= 1.058 × 10−28 m³/unit cell
