A student finds a piece of metal that she thinks is aluminum. She finds the volume to be 245 cm^3 and the mass to be 612 grams.
natta225 [31]

Answer:

Density = 2.5 g/cm³ , The metal is aluminium.

Explanation:

Density is defined as the ratio of the mass and the volume

Thus,

Density=\frac {Mass}{Volume}

Given that:

Mass  = 612 grams

Volume = 245 cm³

Thus, Density is:

Density=\frac {612}{245}\ g/cm^3

<u>Density = 2.5 g/cm³</u>

Metals are shiny with high density.

<u><em>The density of aluminium falls is approx 2.6 g/cm³ and not other metal's density falls in this range. </em></u>

<u><em>The metal is aluminium.</em></u>

<u><em></em></u>

Mario uses a hot plate to heat a beaker of 50mL of water. He used a thermometer to measure the temperature of the water. The wat
Alex777 [14]

Answer:

The boiling point decreases as the volume decreases.

Explanation:

The Temperature - Volume law otherwise called as Charles law is applied, which says that the volume of the given gas at constant pressure is directly proportional to the temperature measured in Kelvin. As the volume increases, the temperature also increases, if the volume decreases, then the temperature also decreases.

As per the Charles law, here the volume is decreased from 50 ml to 25 ml so the boiling point also decreases.

What is the primary cause of diffusion? some substances can dissolve in solvents heat added to a substance random internal motio
Nina [5.8K]

Answer:

random internal motion of atoms and molecule

Explanation:

The primary cause of diffusion is the random internal motion of atoms and molecules.

Randomness of atoms and molecules results in diffusion.

  • Diffusion is the movement of particles from a region of high concentration to that of lower concentration.
  • Substances often tend to spread out over the concentration gradient.
  • Therefore, they have this propensity to be randomized.
