Answer: Thus 663 J of heat is released when 27.6 g 
cools from 83.1 °C to 55.6 °C
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat released = ?
m = mass of substance = 27.6 g
C = specific heat capacity = 
Initial temperature= 
= 
Final temperature = 
= 
Change in temperature ,
Putting in the values, we get:
As the value of q is negative, it means the heat has been released and it is 663J
Answer:
The answer is c
Explanation:
200 divided by 100 is 2 and you can check that by multiplying 2 by 100.
Answer:
An unsaturated solution can dissolve more solute at the given temperature. If you add more solute until the solution will dissolve no more at that temperature, it is saturated solution.
Explanation:
In unsaturated solution, there is capacity of solution to dissolve more solute inside the solution. In saturated solution, there is no capacity of a solution to dissolve any further solute at a given temperature. This capacity is increased by heating the solution so more solute will be dissolved. This is called supersaturated solution.
They have a mass for the particles
There are no totally elastic collisions
There are intermolecular forces
