In order to build a hypothesis, Joan should take an educated guess at what the effect of adding salt to the water will be on the water's boiling point. For example, the hypothesis may be,"The boiling point will increase". This hypothesis is one that can be verified or rejected via experimentation. The next step for Joan would be to set up an experiment to test this hypothesis.
Answer: The correct answer is B- The ions are free to move in water and carry an electric charge.
Answer:
Explanation:
We shall find the volume of stored gas at atmospheric pressure .
P₁ V₁ = P₂ V₂
15.5 x 10⁶ x .02 = 10⁵ x V₂ ( atmospheric pressure is 10⁵ Pa )
V₂ = 3.1 m³
volume of one balloon = 4/3 x π r³ , r is radius of balloon
= 4/3 π x .11³
= .050658 m³
no of balloon = total volume to be filled / volume of one balloon
= 3.1 / .050658
= 61 .2
= 61
For velocity vs time graphs, you can calculate displacement by finding the area between the line and the x-axis (time line). You should be able to recognize that space between the lines as a triangle, trapezoid, square, or rectangle and use the respective area formulas for these shapes.
