Answer:
D) C6H6
Explanation:
The strength of intermolecular forces between particles affects physical properties of substances such as boiling point, melting point, surface tension, and vapor pressure. Which substance has the highest melting point
A) C2H5O
B) C2H6
C) H2O
D) C6H6
C2H5O has a melting point of
C2H6 has a melting point of
H2O
has a melting point of
c6h6 has a melting point of
benzene as the highest melting point
When molecules are tightly packed together, a substance has a higher melting point than a substance with molecules that do not pack well. ... Molecular mass also affects the melting point. , smaller molecules melt at lower temperatures than larger molecules.
melting point is the temperature at which a substance coexist as both solid and liquid without any noticeable change in temperature

Answer:
2.98 second
Explanation:
The severity index is defined by :
a is dimensionless constant that equals the number of multiples of g
Conditions are given as :
Initial velocity, u = 0
Acceleration, a = 34 m/s²
Final velocity, v = 16.4 km/h = 4.56 m/s
We can find t from the above data as follows :
As a is the acceleration that is multiple of g.
So,
So,
Severity index,
Hence, the severity index for the collision is 2.98 seconds.
