Which statement correctly describes the movement of thermal energy according to the second law of thermodynamics? The natural te

ndency of systems is for heat to flow from a cooler object to a warmer one. The natural tendency of systems is to evenly distribute energy until the objects are the same temperature. The natural tendency of systems is for heat to flow continuously between objects of the same temperature.

Answer:

The correct answer is:

The natural tendency of systems is to evenly distribute energy until the objects are the same.

Explanation:

Thermal equilibrium

When ever two bodies differing in temperatures comes in contact with each other heat flow takes place from hotter body to cooler body in order to establish an equilibrium in which temperature of both the bodies becomes constant.

According to second law of thermodynamics:

When the energy of the system increases, matter moves more freely and change in entropy that is disorderliness of the system increases.

This increase in entropy is due to the energy possessed by the matter particles which has resulted in their motion or movement

With this increase in entropy of system, system will start interacting with its surroundings .And this interaction will results in evenly distribution of energy in its surroundings.

What happens to the appearance of an object as it gets hotter?
lana [24]

Answer:

Explanation:

When an object is heated then it becomes brighter and bluish compared to the initial condition. This happens because when an object is given heat then the electron in the ground state gets excited and reaches some higher state. After reaching a higher state electron make the transition to lower state and simultaneously exhibit the color which is visible with naked eyes.

Two iron bolts of equal Mass one at a hundred see another at 55 Sierra place in the insulated cylinder assuming the heat capacit
malfutka [58]

Answer:

T_2 = 77.5c

Explanation:

From the question we are told that

Temp of first boltsT_1=100

Temp of 2nd bolt T_2=55

Generally the equation showing the relationship between  heat & temperature is given by

  q=cm \triangle T

Generally heat released  by the iron bolt  = heat gained by the iron bolt

Generally solving mathematically

     -(0.45*m* (T_2-100  \textdegree c)) = 0.45*m*(T_2 -55\textdegree c)

     -(T_2-100 \textdegree c)) = (T_2 -55 \textdegree c)

      T_2 +T_2= 100 \textdegree c+55 \textdegree c

      T_2=\frac{155 \textdegree c}{2}

      T_2 = 77.5 \textdegree c

Therefore T_2 = 77.5 \textdegree c is the final temperature inside the container

An object has more momentum if it has which of the following?
maks197457 [2]

Answer:

C.) A high velocity and Large mass.

Explanation:

Momentum of any object is defined by following formula

Here :  m = mass of object

v = velocity of object

now we know that since momentum is product of mass and velocity

So in order to have more momentum we need the value of this product to be more.  So this product will me large is both the physical quantity will be more in magnitude. So if mass is large and velocity will be more then the product of them will be large and hence the momentum of object will be more. Btw I had that question too.
