In a density experiment, a student needs to find the density of a container of blueberries. The student gets the mass of the blueberries on a scale.
What is the next step to finding the density of the blueberries
The student will need to use a beaker and a computer to find the volume and
then calculate density.
The student will need to use a graduated cylinder and the displacement method
to find the volume, then calculate density.
The student will need access to a hot plate to heat the water that will be in a
beaker so that the fruit will float and then she can calculate density.
The student will need to use a graduated cylinder, test tubes, and a graduated
beaker to find out the volume of the fruit and then calculate density.

Which table is the table that has the correct physical properties of metals, non-metals, and metalloids
Two students make hot liquid . One students pours the hot liquid into a white foam cup. the other student pours the hot liquid into a silver metal cup. The metal cup become really hot while the foam cup can be held with no problems. What is the best explanation for this
heats up much faster than the metal cup
is a better insulator than the metal cup
is a better conductor of heat than the metal cup
has a specific heat that is similar to that of the metal cup
