What do climatologist study about fossil seashells in rock sediments to learn about climate
ludmilkaskok [199]

Answer:

What information can climatologists learn from fossils? Fossils of plants and animals can show adaptations that organisms had for a particular type of climate that existed millions of years ago. Climatologists look at many pieces of evidence to study climate change. These pieces of evidence can support each other.

A block of metal has a mass of 0.0694 kg. It displaces 3.6 mL of water. What is it’s density in g/cm^3
Ivan

Answer:

19.28 g/cm^3 to the nearest hundredth.

Explanation:

The volume of water displaced = the volume of the metal.

density = mass / volume

0.0694 kg = 0.0694 * 1000

=  69.4 g.

Density = 69.4 / 3.6

= 19.28 g/cm^3.

A gas with a volume of 8 L at a temperature of 473K is switched to a new container with a temperature of 350K. If the pressure r
Digiron [165]

Answer:

The new  volume is 5.92 L,  which is approximately 6 L

Explanation:

As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.

So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:

  • If the temperature increases the volume increases
  • If the temperature decreases the volume decreases

Mathematically this is expressed by:

\frac{V}{T}=k

When you want to study two different states, an initial and a final one of a gas, this law is expressed by:

\frac{V1}{T1} =\frac{V2}{T2}

In this case:

  • V1: 8 L
  • T1: 473 K
  • V2: ?
  • T2: 350 K

Replacing:

\frac{8 L}{473K} =\frac{V2}{350K}

Solving:

V2=350K*\frac{8L}{473K}

V2=5.92 L

<u><em>The new  volume is 5.92 L,  which is approximately 6 L</em></u>
