Describe and explain how the movement and arrangement of the particles in a block of ice change as the ice melts to form liquid water. In your answer, include ideas about energy transfer.

Answers

Answer:

Ice is water in solid phase, in this phase, the particles are very close together and relatively in fixed positions.

As the temperature starts to increase (thermal energy), also does the kinetic energy of the particles (so we have a change from thermal energy to kinetic energy), so they start to move "more", and the position of the particles starts to be less "fixed". There is a point where the particles have enough energy, and this point is where the phase of the water changes from solid to liquid phase (the fusion point). After this point the water can not hold his shape, and takes the shape of the container where it is.

A kayaker paddles at 4.0 m/s in a direction 30° south of west. He then turns and paddles at 3.7 m/s in a direction 20° west of south.What is the magnitude of the kayaker’s resultant velocity? Round your answer to the nearest tenth.

___m/s
What is the direction of the kayaker’s resultant velocity?

___ ° south of west
please help

Answers

The magnitude of the kayaker's resultant velocity is 4.96 m/s.

The direction of the kayaker’s resultant velocity from the triangle is 20⁰ South of west.

Resultant velocity

The magnitude of the kayaker's resultant velocity is calculated by drawing the vector representation of the velocity to form a triangle, with side lengths of 3.7 m/s and 4 m/s, with 80⁰ angle between the two sides.

Let the resultant velocity = R

$R^2 = 3.7^2 + 4^2 - 2(3.7 * 4)* cos (80)\n\nR^2 = 24.55\n\nR = √(24.55) \n\nR = 4.96 \ m/s$

The direction of the kayaker’s resultant velocity from the triangle is 20⁰ South of west (alternate angles).

Which of the following is an example of a decomposition reaction?a. photosynthesis
b. digestion
c. polymerization
d. exchange of ions between two compounds

Answers

The answer is (b) digestion.
A decomposition reaction is a process in which a single compound breaks into two or multiple elements or compounds. A best example is digestion where a large insoluble food molecules breakdowns into small water-soluble molecules so that they can be absorbed into the watery blood plasma.
