Which of the follow describes what happpens to the kinetic energy of water when it changes from the solid state to a liquid stat
Anestetic [448]

Answer:

Kinetic energy increases.

Explanation:

In a solid, molecules do not have much room to move. They are very slow moving, which means that kinetic energy is low. In a liquid, molecules have more room to move. They are able to move faster than a solid, which means that kinetic energy is low.

From greatest to lowest kinetic energy:

gas, liquid, solid

How many valence electrons are in the element gallium? explain how you determined the number.
Natasha2012 [34]

Answer:

three valence electrons

Explanation:

Gallium has three electrons in the outer energy level and therefore has three valence electrons. The identification of valence electrons is vital because the chemical behavior of an element is determined primarily by the arrangement of the electrons in the valence shell.

The freezing temperatures for water for Celsius and Fahrenheit scales are 0ºC and 32ºF. The boiling temperatures for water are 1
ddd [48]

Answer:

Therefore the required function is

C= \frac{5}{9} (F-32)

Therefore 25°C=57°F

Explanation:

F denotes temperature of Fahrenheit and C denotes temperature of Celsius.

\frac{C-0}{100-0} =\frac{F-32}{212-32}

\Rightarrow C= \frac{100}{180} (F-32)

\Rightarrow C= \frac{5}{9} (F-32)

Therefore the required function is

C= \frac{5}{9} (F-32)

Putting C=25°C in above equation

25=\frac{5}{9} (F-32)

\Rightarrow 25 \times \frac{9}{5} = F-32

⇒45 =F-32

⇒F=32+45

⇒F=57

Therefore 25°C=57°F
