Answer:

C. Is an inward force that tends to minimize the surface area of a liquid

Explanation:

Surface tension is a skin-like proper of water that is explained by its property or ability to form hydrogen bonds. The water molecule has the ability to bind the molecules from all sides that surrounds it.

The force of action on each of the molecules is balanced. The surface tension is a more inward phenomenon and it holds the droplet in a spherical shape.

If 0.507J of heat leads to a 0.007 degree C change in water, what mass is present?

Ivanshal [37]

Answer:

17.3 g

Explanation:

<u>Given the following data;</u>

Quantity of heat, Q = 0.507 J
Temperature = 0.007°C
Specific heat capacity of water = 4.2 J/g°C

Mathematically, Heat capacity is given by the formula;

$Q = MCT$

Where;

Q represents the heat capacity or quantity of heat.
M represents the mass of an object.
C represents the specific heat capacity of water.
T represents the temperature.

Making "M" the subject of formula, we have;

$Mass, \ m = \frac {Q}{CT}$

Substituting the values into the formula, we have;

$Mass, \ m = \frac {0.507}{0.007*4.2}$

$Mass, \ m = \frac {0.507}{0.0294}$

<em>Mass, m = 17.3 grams</em>

Which two terms relate and why? Energy level, neutron, spectral line

andre [41]

Energy level and spectral line

Explanation:

The energy levels and their spectral lines are related.

Based on the Bohr's model of the atom, he suggested that electrons occupy specific spherical orbits.

These orbits are called energy levels around the nucleus.

The spectral lines are the different colors emitted by atoms when they absorb or lose energy.

Electrons can transition between different energy levels when they acquire enough energy that corresponds to that of the energy level
By doing so, they emit energy in the process and this is seen as visible spectral lines.
Spectral lines are usually studies in order to gain more information about the properties of atoms.
