Change of state occurs when heat is supplied or removed from a substance.

<h3>What is change of state?</h3>

Change of state refers to the changes that occur when a substance changes from one physical state to another due to changes in its temperature.

It is also known as phase change.

Phase Change can also be defined as change from one state to another without a change in chemical composition.

Some of the phase changes include:

  • Freezing: when liquid changes to solid
  • Condensation: when gas changes to liquid
  • Melting: when solid changes to liquid
  • Evaporation: when liquid changes to gas

The other terms associated with phase change include:

  • Boiling point: the temperature at which vapor pressure becomes high that causes bubbles to form inside the body of the liquid
  • Freezing point: temperature wherein a liquid solidifies
  • Melting point: the temperature at which solid turns into a liquid.

Can someone help me with number 1 and 2 plz!
GalinKa [24]

Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left.  If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar.  We want to find the sum of the forces acting on the object.  In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

Which element melts at room temperature?
just olya [345]
Francium is an element that melts at room temperature. Francium is a highly reactive element, and only contains one valence electron, which is very ironic in my opinion.
