1: Copy and paste the material below into your submission box.

2: Type your responses to each of the following questions from your lab. Your hard copy if for you to keep and study.

Pre LAB Questions:

1. Why is it called a “regular” solid, as opposed to an “irregular” solid? 

 

PROCEDURE:

  1. Record the number of your solid and then find its mass.  Record the mass in the data table. 
  2. Measure the length, width, and height of the solid.  Make your best measurements and record to the nearest 0.01 cm.  Both you and your partner should verify these measurements.
  3. Calculate the volume of the solid and record in the data table.
  4. Use the mass and volume data to determine the density of your solid.

 

DATA TABLE: Mass and Measurements of a Regular Solid

 

Solid # _____

Mass (g)

 

Length (cm)

 

Width (cm)

 

Height (cm)

 

Volume (cm3)

 

Density (g/cm3)

 

 

 

POST LAB QUESTIONS:

  1. Intensive properties do not change with the size of a sample while extensive properties do.  Is density an intensive or extensive property?  Explain your reasoning.

 

 

  1. Suppose you are given a larger block of the same solid material.  Would you expect its density to be about the same as the block in this lab?  Why or why not?

 

 

 

  1. The density of water is 1.0 g/mL.  Would your block float or sink in water?  Support your answer.
