Mr. Keans's class is doing a lab to determine the identity of an unknown metal. Use the table to help determine
the identity of a metal that has a mass of 89 grams and occupies 10 cm of space.
O Nickel
O Silver
O Lead
O Mercury

Explanation:

First, we must find the density of the unknown metal.

Density is found by dividing the mass by the volume.

The mass of the metal is 89 grams and the density is 10 cubic centimeters.

Substitute the values into the formula.

Divide.

Now we know the density and can identify the unknown metal.

The density matches nickel's density. Therefore, this metal must be nickel.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
