How does adding more of a substance affect it's density?

I’m going to use molasses as an example of a substance.

The mass and volume both change when changing the amount of molasses.
However, the density does not change. This is because the mass and volume increase at the same rate/proportion!

Even though there is more molasses (mass) in test tube A, the molasses also takes up more space (volume). Therefore, the spacing between those tiny particles that make up the molasses is constant (does not change).

The size or amount of a material/substance does not affect its density.

Adding more of a substance has no effect on its density.  The formula for density is:

Density = (mass) divided by (volume).

If you doubled the volume of your sample of the substance, then you also doubled the mass of the sample.  So when you divide (mass) by (volume), you still get the same number.  The density doesn't change.

GrogVix [38]

The distance from Buzău to Iaşi is 72 km. Find out the time a vehicle travels this distance if it has a speed of 72 km per hour. Expresses the speed in the unit of measurement in SI. I give the crown! Thank you

Answer:

3600seconds

Explanation:

Given parameters:

Distance  = 72km

Speed  = 72km/hr

Unknown:

Time it takes for the vehicle to travel the distance  = ?

Solution:

Speed is the distance divided by time;

               Speed = \frac{distance}{time}

             time  =\frac{distance}{speed }  

 Insert the parameters;

         time  = \frac{72}{72}  = 1hr

The SI unit of time is in seconds;

3600 seconds is 1hr

The time is 3600seconds
