Answer:

Matter in its solid state has the lowest amount of thermal energy (for that type of matter). Because solids have less thermal energy than liquids or gasses, the atoms in their solid state move very little.

densk [106]

<h3><u> Answer</u>;</h3>

= 4.0 L

<h3><u>Explanation;</u></h3>

Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to pressure at a constant temperature.

Therefore; <em>Volume α 1/pressure</em>

<em>Mathematically; V α 1/P</em>

<em>V = kP, where k is a constant;</em>

<em>P1V1 = P2V2</em>

<em>V1 = 0.5 l, P1 =203 kPa, P2 = 25.4 kPa</em>

<em>V2 = (0.5 × 203 )/25.4 </em>

<em> = 3.996 </em>

<em> ≈ </em><em><u>4.0 L</u></em>

In bullet points: explain the difference between thermal energy, heat and temperature.

sergeinik [125]

Thermal Energy- is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated.

Heat-energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. Heat energy can be transferred from one object to another. The transfer or flow due to the difference in temperature between the two objects.

Temperature- is a measure of how hot or cold something is; specifically, a measure of the average kinetic energy of the particles in an object, which is a type of energy associated with motion.

In a common laboratory experiment in general chemistry students are asked to determine:_____.

Alex787 [66]

<h3>The <u>complete question</u> would be:</h3>

In a common laboratory experiment in general chemistry, students are asked to determine the relative amounts of benzoic acid and charcoal in a solid mixture. Benzoic acid is relatively soluble in hot water, but charcoal is not. Devise a method for separating the two components in the mixture.

<h3>The <u>solution</u> for that would be:</h3>

First you put the mixture in hot water and allow the benzoic acid to separate. Next funnel it and then see what's on the funnel paper. Lastly, heat the leftover water and see what's left after it evaporates.

<h3><u>What are laboratory experiments ?</u></h3>

Using controlled surroundings to test theories, researchers may develop laboratory experiments.
Laboratories are rooms or specially constructed facilities within buildings that are often found on college and university campuses and are utilized for academic research.
It's crucial to differentiate between experiments and other kinds of research investigations carried out in lab settings.
Even if a research study takes place in a lab, it is not always an experiment.
In order to evaluate causal conclusions regarding the links between independent and dependent variables, laboratory studies, like all genuine experimental designs, use procedures of random assignment of participants and control groups.
