Answer:

Evaporation

Explanation:

- The sugar molecules are more massive than the water (H2O) molecules. This can be compared across using their Molecular mass (Mr). Since, sugar molecules are more massive they are slower than water (H2O) molecules.

- As Heat is transferred to the the solution the temperature of the mixture rises that increases the speed of all molecules inside the mixture. ( Boltzman expression).

- As the speed of the molecules of water is relatively faster than those of sugar molecules, the molecules of water start to break free from their bonds of liquid and escape into the atmosphere ( evaporation) as gaseous molecules ( steam ).

Answer:

Water turns into vapor leaving sugar behing.

Explanation:

During the kinetic theory of motion of particles during the boiling of a homogeneous mixture of sugar and water, molecules starts moving faster because of the sudden increase in temperature, making the molecules to spread further apart from each other. As sugar water is been heated the water will suddenly turn into vapor leaving the sugar behind.

The electrons involved in the formation of a chemical bond are called
tatiyna

Answer: Valence electrons

Valence electrons are those that are in the outermost or superficial layer of the atom, which means they have the highest energy compared to those of the inner layers.

Because of their position, it is easier for these electrons to interact with other atoms of their own element as well as different elements. This is done through the process of forming bonds when being attracted by other atoms.

When a rocket is traveling toward a mountain at 100 m/s, the sound waves from this rocket's engine approach the mountain at spee
Charra [1.4K]

Answer:

The correct option is C

Explanation:

From the question we are told that

  The initial speed of the rocket is  v_i = 100 m/s

    The speed of the rocket engine sound is V

    The final speed of the rocket is  v_f = 200 \ m/s

The speed of the sound at v_f would still remain V this because the speed of sound wave is constant and is not dependent on the speed of the observer(The mountain ) or the speed of the source (The rocket ).

  A clear example when  lightning strikes you will first see (that is because it travels at  the speed of light which is greater than the speed of sound) but it would take some time before you hear the sound of the   lightning

Here we see that the speed of the lightning(speed of sound) does not affect the speed of the sound it generates

Define moment of momentum. at which condition is it's magnitude zero?​
ololo11 [35]

Let's start with the concept of momentum. What is it? Linear momentum in physics is mathematically written as a product of mass and velocity of an object. Now let us suppose a body of mass m is moving in an inertial frame of reference with velocity v. Consider the fact that no external force is acting on the system. The momentum of this body is given by mv, where m is the mass and v is its velocity. In case of simple real world problems not delving into the realms of relativity, mass is a conserved quantity and it cannot be zero. Hence the velocity of the body must be zero and hence the momentum.

However, photons are considered to have a rest mass zero.

However note the point carefully "rest mass". A body in motion cannot have mass to be zero.
