What is the relationship between Celsius and kelvin
Inga [223]

The relationship between Celsius and kelvin is that degrees Kelvin is equal to degrees Celsius + 273.15. That means that the freezing point of water (0°C) is 273.15° kelvin. This makes an additive relationship between the two quantities, so quantities such as the boiling point and freezing point of water are the same distance apart on the Kelvin scale (100 degrees). This means that kelvin has the same magnitude as Celsius.

Match each term to its description.
stepladder [879]

Based on ecological studies, the definitions below applies to the given terms:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

Ecology is the study of living things and their interactions with their environment.

Some terms in ecology include:

  • Peak phenomena: this is when a population grows at a fast rate, then quickly drops when the resources run out
  • Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
  • Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
  • Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

To reduce 16 ounces of a 25% solution of antiseptic to a 10% solution, how much distilled water should a nurse add?
NemiM [27]
<span>Let x = amt of distilled water
:
A simple equation
.25(16) = .10(x+16)
4 = .10x + 1.6

4 - 1.6 = .1x
2.4 = .1x
x = 2.4/0.1
x = 24 oz of distilled water
:
:
Prove this by seeing the amt of antiseptic is the same (only the % changes)
.25(16) = .10(24+16)
4 = .1(40)
