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.

Answer: Fe2O3
Explanation:
100 grams of iron ore = 30.06% oxygen
100 - 30.06 = 69.94% iron
Mr of Iron = 55.85
Mr of Oxygen = 16
Iron = 69.94/55.85 = 1.252
Oxygen = 30.06/16 = 1.879
1.879 / 1.252 = 1.5 of Oxygen
1.252/1.252 = 1 of Iron
we can write that as Fe1O1.5 but we can't use decimals therefore we have to multiply the whole thing by 2
So it comes out to be Fe2O3
Being imaginative in doing science is using your knowledge and creativity to make innovative ideas, while psuedoscience is using sources that are not true and do not use actual science. Example being ads that say "Wow you will not believe what how this oil cured cancer!".
It proposed that the positive charge was concentrated in the nucleus.
i just took the test. this is right.
Answer:
Respiración anaerobica
Explicación:
Las nuevas especies carecen de mitocondrias, por lo que realizan respiración anaeróbica porque en las mitocondrias solo ocurre la respiración aeróbica mientras que la respiración anaeróbica ocurre en el citoplasma de la célula. Trabajar en armonía es muy importante para el funcionamiento normal de su cuerpo. Por ejemplo, el funcionamiento combinado del sistema circulatorio y excretor. ambos sistemas hacen su trabajo mutuamente y por eso hay armonía en el cuerpo.
