Answer:
The sample of lithium occupies the largest volume.
Explanation:
Given the densities for the four elements, we have the expression
that shows the relationship between mass and Volume to express the density of an element.
For each element we have:




The problem says that all the samples have the same mass, so:

it means that m is a constant
Now, solving for the Volume in each element and with m as a constant, we have:












If we assume m = 1g, we find that:




So we can see that the sample of lithium occupies the largest volume with 1.88mL
Note that m only can take positive values, so if you change the value of m, always will be the lithium which occupies the largest volume.
Answer:
As the average kinetic energy increases, the particles move faster and collide more frequently per unit time and possess greater energy when they collide. Both of these factors increase the reaction rate. Hence the reaction rate of virtually all reactions increases with increasing temperature
HOPE THIS HELPED!!!!!!!!!!!!!! XDDDDD
The unit used to measure the volume of a solid is cubic centimeters.
Answer: C. Heat transfers thermal energy from the student's hand to the ice.
Explanation: It seems confusing; b and c seem to be saying the same thing, but the definition of heat is the transfer of thermal energy from a warmer object to a colder object.
