Temperature will raise and water will evaporate
I would say B but I am not sure so sorry if it is wrong!!
Explanation:
When a brick is heated to a temperature between 20°C and 150°C, it loses most of the water added to the clay during the preparation phase. ... When the temperature starts to rise over 600°C, chemical changes begin to occur in the clay which give the brick colour, hardness and durability.
Answer:
a. 0.191 ppm b. 4.962 ppm c. 0.0385 ppm
Explanation:
a. 17 g of calcium = 0.017 mg. 89 mL = 0.089 L.
So our concentration = 0.017 mg/0.089 L = 0.191 mg/L = 0.191 ppm
b. 0.65 mg of caffeine in 131 mL = 0.131 L.
So our concentration = 0.65 mg/0.131 L = 4.962 mg/L = 4.962 ppm
c. 0.35 mg of trace particle in 91 dL = 9.1 L.
So our concentration = 0.35 mg/9.1 L = 0.0385 mg/L = 0.0385 ppm
