Answer:

Transferring heat to a body.

Step by step answer:

Entropy refers to the degree of disorder of a system. This increases when we move from a state of greater order to one of a greater degree of disorder.

By heating a body, this causes the energy of the body to increase. This means that the speed of the molecules that compose it increases and makes them collide more frequently between them, creating an increase in the degree of disorder that exists.

A clear example of heat transfer is when a body changes its state and moves from an orderly state to one of greater disorder.

 For example:

  • Moving from a solid state to a liquid state:

Melt an ice cube

  • Move from liquid to gaseous:

Heat water until it starts to boil and turns into steam

You do not necessarily have to change the state to increase the entropy.

For example when heating water without boiling.

The first energy level holds how many electrons?
Mama L [17]

Answer: two electrons

Explanation:  The first principal energy level contains only an s sublevel; therefore, it can hold a maximum of two electrons. Each principal energy level above the first contains one s orbital and three p orbitals. A set of three p orbitals, called the p sublevel, can hold a maximum of six electrons.

Two wooden boxes of equal mass but different density are held beneath the surface of a large container of water. Box A has a sma
Novay_Z [31]

Answer:

Box A

Explanation:

Let mass of each wooden box =m

Density of box A=\rho_A

Density of box B =\rho_B

\rho_A

Density,\rho=\frac{m}{V}

V_A=\frac{m}{\rho_A}

V_B=\frac{m}{\rho_B}

Density of inversely proportional to volume.

The volume of box with smaller density is larger than the volume of box with large density.

V_A>V_B

When the boxes are submerged under water.

Then, the buoyant force=\rho_l Vg

Where V=Volume of displace fluid.

\rho=Density of fluid

Buoyant force of box A=\rho_lV_Ag

Buoyant force of box  B=\rho_lV_Bg

Force=Buoyant force

ma_A=\rho_lV_Ag

ma_B=\rho_lV_Bg

Acceleration is directly proportional to volume.

Therefore,the box with large volume has greater acceleration.

Hence, the box A has greater acceleration.
