Liquids have more kinetic energy in their particles compared to solids. this allows the particles to move more freely, hence why they are fluids
Liquids diffuse from a region of high concentration to a region of low concentration, until equilibrium is reached
When heat is applied the particles gain more kinetic energy so they now have enough energy to overcome the bonds holding them in the liquid. this means they can evaporate off
No, hydrogen can only hold one bond and that's it. It only needs to be paired with one bond.
Answer:
The total heat required is 3.4 kJ
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. So, the amount of heat a body receives or transmits is determined by:
Q = c * m * ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case you know;
- c= 4

- m= 10 g
- ΔT= Tfinal - Tinitial= 10 C - 0 C= 10 C
Replacing:

Solving:
<em>Q1= 400 J</em>
On the other hand, you must determine the heat required to convert 0 ∘ C of ice to 0 ∘ C of liquid water by:
Q2=m*heat of fusion
Q2=10 g* 300 
<em>Q2= 3,000 J</em>
The total heat required is:
Q= Q1 + Q2= 400 J + 3,000 J
Q= 3,400 J= 3.4 kJ (1 kJ= 1,000 J)
<u><em>The total heat required is 3.4 kJ</em></u>
Answer:
Zinc
The element was probably named by the alchemist Paracelsus after the German word Zinke (prong, tooth).
