The glass capillary having one end closed and one open end is generally used for the determination of melting point of the sample. From the open end, the sample is put into the capillary, the sample must be firmly packed as the melting point is an intrinsic property that means it is independent of sample size. So, in order to determine the melting point of the sample small sample in the capillary is sufficient to measure the melting point of the sample. To obtain the more consistent value of melting point one must pack the sample firmly in the capillary.
Hence, when determining the melting point of a substance, one should use a small sample in the capillary and the sample should be firmly packed.
<em>Answer:</em> 8 (feet)
<em>Explanation:</em>
24 inches = 2 feet
48 inches = 4 feet
12 inches = 1 foot
To find volume you do Base * Width * Height
2*4*1 = 8
Hope this helps!
The answer is Latitude (B)
Answer:
A
Explanation:
You want an equation that includes both V and T. Charles' Law states that V =kT or V₁/T₁ = V₂/T₂, so this is the best formula to use.
B: The Combined Gas Law is p₁V₁/T₂ = p₂V₂/T₂ will work, but it's overkill for the situation. You can assume any constant value for the pressure, and it will cancel from each side of the equation,
C is wrong. Boyle's Law is p₁V₁ = p₂V₂. It does not include the temperature.
D is wrong. Gay-Lussac's Law is p₁/T₂ = p₂/T₂. It does not include the volume.
Answer:
The hydroxyl ions (OH-) released will combine with any hydrogen ions (H+) in the solution to form water molecules (OH- + H+ = H2O).
