Energy is invisible yet it's all around us and throughout the universe. Energy can never be made or destroyed, but its form can be converted and changed.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
Energy transformation, also known as energy conversion, is the process of changing energy from one form to another. In physics, energy is a quantity that provides the capacity to perform work or provides heat.
When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat. This consent is known as “hidden energy”.
Answer:
<em>Butane has only two isomers and pentane has just three, but some hydrocarbons have many more isomers than these. As you increase the number of carbon atoms in a hydrocarbon, the number of isomers quickly increases.</em>

Neutralization reaction takes place between an acid and a base to form salt and water.
In the given reaction the acid is hydrochloric acid HCl and the base is aluminum hydroxide (Al(OH)
).
The correct balanced equation for the neutralization reaction that occurs between aluminum hydroxide and hydrochloric acid can be represented as:
Al(OH)can give 3 hydroxide, 
ions which can neutralize the 3 
ion produced by 3 HCl molecules giving 3 mole of water and the salt aluminum chloride, AlCl.
Therefore the correct option will be.
D. Al(OH)3 + 3 HCl (aq) --> AlCl3(aq) + 3 H2O(l)
There are questions about the external validity of the results because single-subject experiments frequently only involve a small number of subjects.
<h3>What is experimentation with a single subject?</h3>
A type of quantitative research known as single-subject studies includes closely examining each participant's behavior in a small sample size. It should be noted that the phrase "single-subject" does not necessarily suggest that only one participant is being examined; rather, it usually refers to a group of two to ten.
<h3>What does a single-subject research design aim to achieve?</h3>
Single subject research design is a sort of research methodology that involves monitoring a single phenomena repeatedly over time (often a behavior), and it is typically used to test interventions.
<h3>What features distinguish single-subject studies?</h3>
Changes on the DV can be measured using data gathered before, during, and after the intervention.
