Elena-2011 [213]3 years ago
8 0

The average kinetic energy <span>K.E(<span>av)</span></span> is measured by:

<span>K.E(<span>av)</span>=<span>3/2</span>RT</span>

the average kinetic energy is directly proportional to the temperature<span> .</span>

<span>When water freezes, the temperature decreases and therefore, the average kinetic energy will also decreases as well.</span>

What three variable factors determine the force of gravity between any two objects?
brilliants [131]
The force of gravity between two objects is:
F = G*m1*m2/r^2

So, it is dependent of the two masses and the distance between their centers of mass.

The energy produced by the internal motion of atoms? electrical , thermal, chemical, nuclear
alekssr [168]

Answer:

Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth. Motion energy is energy stored in the movement of objects. so the answer is thermal energy

According to the second law of thermodynamics, it is impossible for ____________. According to the second law of thermodynamics,
Tomtit [17]

Answer:

It's impossible for an ideal heat engine to have non-zero power.

Explanation:

Option A is incomplete and so it's possible.

Option B is possible

Option D is related to the first lae and has nothing to do with the second law.

Hence, the correct option is C.

The ideal engine follows a reversible cycle albeit an infinitely slow one. If the work is being done at this infinitely slow rate, the power of such an engine is zero.

We can also stat the second law of thermodynamics in this manner;

It is impossible to construct a cyclical heat engine whose sole effect is the continuous transfer of heat energy from a colder object to a hotter one.

This statement is known as second form or Clausius statement of the second law.

Thus, it is possible to construct a machine in which a heat flow from a colder to a hotter object is accompanied by another process, such as work input.
