Explain how scientific knowledge and reasoning can help us make difficult decisions.
ch4aika [34]
<span> Scientific reasoning consists of observation, forming a workable hypothesis and arriving at a conclusion. Almost without exception major scientific discoveries were made and are being made today based on these same precepts. It only seems logical when an individual makes a difficult decision he/she will apply all or part of these processes. Let;s say that you want to make someone;s acquaintance to possibly become serious. Certainly, you would begin by quietly observing them, then you might make a hypothesis, "This person might make a good companion for me." Then in your conclusion you would test your hypothesis and proceed as directed. THis may be a bit simplistic, and I hope that it helps.</span>

Properties of a substance which can be measured or observed without altering the identity of the substance being measured are __
rosijanka [135]

Answer:

The correct answer is physical properties and/or phase properties.

Explanation:

Chemical properties can alter the substance (if you burn wood, it becomes ash and is no longer wood).

Reactive properties are also chemically changing the substance.

Phase properties are where the element can be in solid, liquid, or gas form so these could also be an answer.

What is the equilibrium condition in which a gas holds all the water vapor molecules that it can?
faust18 [17]

The equilibrium state of a gas when it can hold all the molecules of water vapor is known as saturation.

<h3>Which three equilibrium conditions apply?</h3>

A solid substance subjected to three forces with divergent lines of action is in equilibrium if all three of the following three circumstances hold true:

  • Coplanar action lines are present (in the same plane)
  • The paths of action have come together (they cross at the same point)
  • These forces add up to a vector with a total of zero.
<h3>What are equilibrium's first and second conditions?</h3>

An object must satisfy two requirements of equilibrium in order to maintain static equilibrium.

  • First, there must be no net force acting on the item.
  • Second, there must be no net torque pulling on the object.
