Question

define compression and indictors?​

Answer 1

Answer:

An indicator diagram is a chart used to measure the thermal, or cylinder, performance of reciprocating steam and internal combustion engines and compressors.[1] An indicator chart records the pressure in the cylinder versus the volume swept by the piston, throughout the two or four strokes of the piston which constitute the engine, or compressor, cycle. The indicator diagram is used to calculate the work done and the power produced in an engine cylinder[2] or used in a compressor cylinder.

Answer 2

Answer:

The definition of compression is the action or state of being squished down or made smaller or more pressed together. ... When a pile of material is squished together and made smaller and more dense, this is an example of compression.

Indicators are substances whose solutions change color due to changes in pH. They are usually weak acids or bases, but their conjugate base or acid forms have different colors due to differences in their absorption spectra.
