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:
The gravitational potential energy equals the work needed to lift the object.
Explanation:
here we know that
work done is given as
Potential energy is given as
force due to gravity is given as
now here if we plug in the value of distance and force in the formula of work done then we will have
so here we got
so we can concluded that
The gravitational potential energy equals the work needed to lift the object.
Answer:
density is Mg/µL
Explanation:
given data
density of nuclear = kg/m³
1 ml = 1 cm³
to find out
density of nuclear matter in Mg/µL
solution
we know here
1 Mg = 1000 kg
so
1 m³ is equal to cm³
and here 1 cm³ is equal to 1 mL
so we can say 1 mL is equal to 10³ µL
so by these we can convert density
density = kg/m³
density = kg/m³ ×
Mg/µL
density = Mg/µL
Answer:
66.98 db
Explanation:
We know that
L_T= Total signal level in db
n= number of sources
L_S= signal level from signal source.
= 66.98 db
