All you need is a thermometer. If the temperature rises as the reaction goes to completion, then the reaction is exothermic. If the temperature decreases, then it's endothermic.
In science, evidence is any result of an experiment done with the scientific method. Evidence and experiments to acquire evidence are methods by which one can scientifically prove a claim.
To prove that adding HCl to magnesium ribbon results in a chemical change, you can observe the reaction's characteristics: the magnesium will react with hydrochloric acid to produce hydrogen gas, which can be identified by the formation of bubbles. Additionally, the magnesium will dissolve, resulting in the formation of magnesium chloride, indicating a change in the substance's composition. Measuring the temperature change during the reaction can further support that a chemical change has occurred, as exothermic or endothermic reactions typically accompany chemical transformations.
Direct evidence is something that can prove a fact, evidence that someone has seen or heard. Indirect evidence is different because it relates to facts and does not prove a fact on its own. Indirect evidence is also called circumstantial evidence.
They have evidence, but if they cant prove something, even with the evidence, it becomes a theroy, or belief. So sometimes it is based on evidence and fact, sometimes on belief.
Evidence consists of facts, data, or information that supports a claim or conclusion. It can take various forms, such as statistics, research findings, eyewitness accounts, or physical objects. Strong evidence is credible, relevant, and sufficient to prove or disprove an argument.
You need one piece of (true and verifiable) evidence. Infidelity does not depend on a sliding scale. Suspicions do not count as far as the law is concerned. If you cannot prove it, then it is not a fact, it is an opinion.
This evidence demonstrates that epics are narratives of heroic journeys, where the protagonist faces trials and battles with supernatural beings. These journeys often involve themes of courage, heroism, and overcoming adversity through strength and cunning.

The best way to prove employee dishonesty is by keeping a record of evidence that may prove your view. Without evidence or a witness, it may be difficult to prove it.

Evidence can prove, or disprove, the case against you.
proof is a physical truth which noone needs to prove it otherwise. prove is the action taken to have proof.

By giving evidence.
A piece of evidence that is commonly used to prove the law of constant composition is that any sample of water is 88. 71 percent oxygen and 11. 19 percent hydrogen. It was formulated by Joseph Proust.
