What is the difference between an essay and a composition?
An essay is a paper written on a particular subject. A composition is usually the same thing as an essay, just called something different.
The words 'composition' and 'essay' are often used interchangeably, as both are literary forms. An essay is a type of composition, but a composition doesn't always have to be in the form of an essay. A composition can be a poem, short story, argumentative essay, or research paper. An essay is more specific, as it is a personal piece on a specific topic.
Well, basically, pearlite is the eutectic composition of steel, with an overall composition of 0.8% carbon. It is known to consist of two phases, namely: Ferrite (Fe), the room temperature of iron and Cementite(Fe3C). Therefore, the difference between pearlite and cementite is that pearlite is a composition of steel, and cementite is a composition of Pearlite. So cementite is part of pearlite.
An essay is typically scholarly nonfiction, and will be informative. It will often include citation, and unless it is a personal essay, very rarely use the first person. Other forms of writing, such as fiction, will read like a story and occasionally use first person. Poetry and drama take significantly different forms that an essay or a fiction, and the difference between these forms will be stark and recognizable.
