Answer:
r² x h
Explanation:
A can is cylindrical in nature. Using the formula of the volume of the can, we can find this unknown volume.
The volume of cylinder is given as:
Volume of a cylinder = Area x height
Volume of a cylinder = r² x h
Therefore density of the can;
Density = 
Answer:
The patented TRUE-TECH Self-Heating Technology is a simple combination of food grade iron and magnesium powder, salt, and water. When the contents of the water pouch are poured over the heater pad, the Food Heater releases enough heat to warm-up a pre-cooked meal 100 degrees Fahrenheit in approximately 10 minutes.

Answer:
Option-D : <span>Decrease the velocities of the particles, and decrease the space between the particles.
Explanation:
The solid state of matter is composed of particles closely packed with a minimum space between them. This closed packing of particles occur due to strong interatomic or intermolecular interactions between particles. Therefore, solids particles have zero translational and rotational motions and only show vibrational motions. So, decrease in velocity and decrease in space between particles is the right answer for making solids.</span>
Without plastic, we wouldn't have as much of an environmental problem as we have now. Even though plastic has a lot of negatives, it's also made our lives a lot easier over past years. ... Our cars would have been different since a lot of the materials used inside are made out of plastic.
