A chemist encounters an unknown metal. They drop the metal into a graduated cylinder containing water, and find the volume chang
Mashutka [201]

Answer:

The density of the metal is 0.561 g/mL

Explanation:

The computation of the density of the metal is shown below;

As we know that

The Density of the metal is

= \frac{mass}{volume}

where,

Mass = 4.9g

Change in volume = 6.9 mL

Now place these values to the above formula

So, the density of the metal is

= \frac{4.9g}{6.9mL}

= 0.561 g/mL

Hence, the density of the metal is 0.561 g/mL

We simply applied the above formula so that the correct density could arrive

If the bag was made from a metal (like sturdy aluminum foil), do you think it would lose its heat faster or slower than the plas
Luden [163]

I think it would lose its heat faster than the plastic bags because of higher conductivity feature.

<h3>What is conduction?</h3>

Conduction is the process in which heat or electricity is transmitted or transferred through the material of a substance without movement of the material.

We know that metals are good conductors so we can conclude that it would lose its heat faster than the plastic bags bof higher conductivity feature.
