They have the same density because a material, no matter how much of it there is, will always be a certain density. A 40g ball of iron has the same density as a 1g ball of iron.
Answer:
6.66 mL
Explanation:
The increase in the volume is due to the addition of the iron whose volume can be calculated as:
Using,
Density = Mass / Volume
Given that:
Density of Iron = 7.87 g/cm³
Mass of iron = 52.4 g
Thus, volume is:
Volume = Mass / Density = 52.4 / 7.87 cm³ = 6.66 cm³
Also, 1 cm³ = 1 mL
<u>The rise in the volume = 6.66 mL</u>
Answer:
<h3>
Which of the following increases with the increase in the temperature in case of a liquid?</h3><h2>
<em>Va</em><em>pour</em><em> </em><em> </em><em>Pressure</em><em> </em></h2>
Explanation:
When a closed container contains liquid, higher the temperature, higher the evaporation the evaporation will be.
So Vapour Pressure should be the correct answer.
Answer:
A. 8.4
Explanation:
[OH⁻] = 2.6 × 10⁻⁶ Take the negative log of each side
-log[OH⁻] = pOH = 5.59 Apply the pH/pOH relation
pH + pOH = 14.00 Insert the value of pOH
pH + 5.59 = 14.00 Subtract 5.59 from each side
pH = 14.00 -5.59 = 8.41
I think that the answer could be A. X and Y
