pH scale ranges from 0 (highly acidic) – 14 (highly alkaline). The pH of a neutral solution is 7. Acidic solution is represented by a value less than 7 on the pH scale.
pH, quantitative measure of the acidity or basicity of aqueous or other liquid solutions.
Scientists use something called the pH scale to measure how acidic or basic a liquid is.
Although there may be many types of ions in a solution, pH focuses on concentrations of hydrogen ions () and hydroxide ions ().
The scale measures values from 0 all the way up to 14. Distilled water is 7 (right in the middle).

Answer:
they us the pH(potential Hydrogen) scale
Explanation:
Reds are strong acids
yellows are weak acids
green is neutral
blue is kinda basic
and purple is super basic
keep in mind, this is just the litmus paper scale

c feree times distance-
D distance divided by the time
Answer:
a
Explanation:
ability to cause change in matter or the capacity to do work
Answer:
D. Physics
Explanation:
First, let's define all the answer choices.
Biology: Biology is the study of life and living things. Biology deals with the function, growth, origin and more of organisms.
Chemistry: Chemistry is the study of matter, elements, atoms, compounds, molecules and more. Chemistry is also concerned with chemical reactions.
Planetary science: Planetary science is basically the study of planets. This is the study of planets, moons and planetary systems.
Physics: Physics is the study of matter, energy, and their interactions. This helps us to explain and understand things that happen in the universe.
The best choice is D. Physics. Physics is the study of how matter and energy interact.
The D. Physics is the study of how matter and energy interact. It helps us understand how things work and why they behave the way they do.
Physics is a natural science that explores the fundamental principles governing the universe. It studies the behavior of matter, energy, space, and time through the formulation of physical laws and mathematical equations. Physics covers diverse topics, including mechanics, electromagnetism, thermodynamics, relativity, quantum mechanics, and astrophysics, explaining phenomena from the subatomic to cosmic scales.
Thus, it is the study of how matter and energy interact. It is concerned with describing the interactions of energy, matter, space, and time to uncover the fundamental mechanisms that underlie every phenomenon. In simple terms, physics helps us understand how things work and why they behave the way they do.
