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.
Explanation:
,.,
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.
Mass number of an element write in bottom of it!
So, there 80 would be the mass number of ₈₀Br.
Hope this helps!
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:

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

In this case:
- V1: 8 L
- T1: 473 K
- V2: ?
- T2: 350 K
Replacing:

Solving:

V2=5.92 L
<u><em>The new volume is 5.92 L, which is approximately 6 L</em></u>
