Crystallization is a physical change from liquid form to solid form. It is the opposite of melting. This is done by creating a supersaturated solution. You add more solute exceeding its capacity and heat so that all will dissolve. Then, when you cool it down with an aid of the ice, solid crystals will eventually form. The bigger the container the ice, the faster is the rate of crystallization and the bigger the solid crystals would be.
Answer:
0.89821 atm
Explanation:
Psi and atm are units of pressure.
Psi stands for pound force per square inch.
While atm stands for atmosphere.
In order to convert the psi to atm we would divide the given value 14.696.
Given value = 13.2 psi
In atm:
13.2 / 14.696 = 0.89821 atm
¿What? For you bye, i love you, no sabo ingles.
Answer:
1.023 J / g°C
Explanation:
Mass, m = 37.9 g
Temperature increase (change) = 25.0°C
Heat = 969 J
Specific heat capacity , c= ?
The relationship between these quantities is given by the equation;
H = mcΔT
c = H / mΔT
c = 969 / (37.9 * 25)
c = 969 / 947.5 = 1.023 J / g°C
