Chemical reaction by temperature can affect the change of matter. If you increase the temp. you increase the reaction rate. Ex. Burning a marshmallow can cause the fire to break down the chemical bonds.

Physical change by temperature can affect depending on pressure. In terms of malleability, a metal being compressed can be shaped into a different object, but the chemical bonds are still the same.

<h2>Steps:</h2>
  • Remember that Density = mass/volume, or D = m/v

So firstly, we have to find the volume of the rock. To do this, we need to subtract the volume of water A from the volume of the water B. In this case:

  • Water A = 30 mL
  • Water B = 40 mL
  • 40 mL - 30 mL = 10 mL

<u>The volume of the rock is 10 mL.</u>

Now that we have the volume, we can plug that and the density of the rock into the density equation to solve for the mass.

3.678=\frac{m}{10}

For this, multiply both sides by 10:

36.78=m

<h2>Answer:</h2>

<u>Rounding to the tenths place, the mass of the rock is 36.8 g, or C.</u>
