Answer:

c. relative age

Explanation:

Relative age is a method of describing the age of rocks based on their order of appearance in the geologic column.

Events are denoted by their position in the column.

  • The premise of most of the assumptions used relative age determination is based on stratigraphic laws.
  • Absolute age gives numeric ages to rocks.

Since Luisa is comparing the age of people based on their position in her family, she is using the concept of relative dating.

The total pressure in a 1.00 liter container is 725 mm Hg. The container contains water vapor and nitrogen gas. If the partial p
rusak2 [61]

Answer:

Explanation:PRESSURE: atmospheres or mm Hg; 1 atm = 760 mm Hg

TEMPERATURE: Kelvin, K, which is o

C + 273

STP: Standard Temperature and Pressure: 273 K and 1 atm (or 760 mm Hg)

BOYLE'S LAW (temperature is constant): PV = constant

This is an inverse relationship: if one variable increases the other must

decrease.

CHARLES' LAW (pressure is constant): V = constant x T

This is a direct relationship: if one variable increases so does the other.

GAY-LUSSAC'S LAW (volume is constant): P = constant x T

This is a direct relationship: if one variable increases so does the other.

<h2>Every one of this with the constant</h2>

Which of the following is an example of pure research? searching for fuels other than gasoline to power cars producing heat-resi
Sliva [168]
I think the correct answer would be the third option. An example of a pure research would be creating synthetic elements to study their properties. Pure research is also known as fundamental or basic research. It has an exploratory nature wherein it is done without any end use in mind. It is mostly out of the curiosity or intuition of a researcher. Most of the study under this type is aiming to advance an existing knowledge by explaining or identifying the relationship of the variables being studied. It is aimed at improving theories in order to the understanding of a specific  phenomenon.
