Solid : The particles are held together and arranged in a regular pattern. They cannot move from one place to another but only vibrate at their own positions. The spaces between them are very little. Liquid : The particles are close together but they can move from one place to another. The spaces between them are little. Gas : The particles are far apart and move freely in all directions.

What is the relationship between manipulated variable and a responding variable?
The manipulated variable, also known as the independent variable, is the factor that is intentionally changed or controlled in an experiment to observe its effects. The responding variable, or dependent variable, is the outcome that is measured to assess the impact of changes in the manipulated variable. Essentially, the relationship is that changes in the manipulated variable are expected to cause changes in the responding variable. This relationship is fundamental to understanding cause-and-effect in scientific experiments.
What is the factor at changes in an experiment because of a manipulated variable?
The factor that changes in an experiment due to a manipulated variable is known as the dependent variable. This variable is measured or observed to assess the effect of the changes made to the independent (manipulated) variable. By analyzing how the dependent variable responds, researchers can draw conclusions about the relationship between the two variables.
What research methods is used to demonstrate a cause and effect relationship between changes in one variable and the effects on another variable?
To demonstrate a cause-and-effect relationship between changes in one variable and effects on another, researchers commonly use experimental research methods. This involves manipulating an independent variable while controlling for other factors, allowing for observation of changes in the dependent variable. Randomized controlled trials (RCTs) are a prime example, as they randomly assign participants to different groups to assess the impact of specific interventions. Additionally, longitudinal studies can also provide insights into causal relationships over time by tracking changes in variables.
What is the relationship between velocity mass force and acceleration?
Some relations. Newton's laws: F=ma N=mg Free fall: V=gh (free fall) Impact: m1v1+m2v2=m1u1+m2u2 (unelastic impact) Energy: Ek=(1/2)mv2 Ep=mgh
What is one factor that a scientist changes in an experiment is called the?
One factor that a scientist changes in an experiment is called the independent variable. This variable is manipulated to observe its effect on the dependent variable, which is measured in response. By controlling other variables, scientists can establish a cause-and-effect relationship between the independent and dependent variables.
Is the speed of the particles in a substance changes when the temperature changes?
Yes, in fact, particle movement is what heat is.
What is a process by which a substance changes from its liquid state to is gas state by random particle movement?
Evaporation.
How does a change in pressure effects the particle movement?
A change in pressure affects particle movement by altering the density and kinetic energy of the particles in a substance. When pressure increases, particles are forced closer together, which can restrict their movement and increase interactions between them. Conversely, a decrease in pressure allows particles to spread apart, leading to increased movement and potential changes in state, such as from liquid to gas. Overall, pressure changes influence how freely particles can move and how they behave in different states of matter.

What is the relationship between the temperature of a particle and the movement of the picture?
The temperature of a particle is directly related to its kinetic energy, which dictates how fast the particles move. As temperature increases, particles gain energy and move more vigorously, leading to increased motion. This heightened activity can manifest in various ways, such as changes in state (e.g., solid to liquid) or increased diffusion rates in gases and liquids. Therefore, temperature is a key factor influencing the movement and behavior of particles.
How is particle movement related to thermal energy?
Particle movement is directly related to thermal energy. As thermal energy increases, particles gain kinetic energy and begin to move faster and more erratically. This increased movement contributes to the overall temperature of a system and can lead to changes in state, such as melting or boiling.

What is the relationship between constant acceleration a speed v and distance r from the origin for a particle travelling in a circle?
For a particle traveling in a circle at a constant speed, the acceleration is toward the center of the circle, known as centripetal acceleration. The acceleration is determined by the formula a = v^2 / r, where v is the speed of the particle and r is the distance from the origin (radius of the circle). This relationship shows that as the speed or radius changes, the centripetal acceleration will change accordingly.
What is the relationship between the movement of charged particles and the change in their electric potential or kinetic energy?
The movement of charged particles can lead to changes in their electric potential or kinetic energy. When charged particles move in an electric field, they can experience changes in their electric potential energy. Additionally, the movement of charged particles can also result in changes in their kinetic energy, which is the energy associated with their motion.
How does the relationship between work and electric potential energy affect the behavior of charged particles in an electric field?
The relationship between work and electric potential energy influences the movement of charged particles in an electric field. When work is done on a charged particle, its electric potential energy changes, affecting its behavior in the electric field. Charged particles will move in a direction that minimizes their electric potential energy, following the path of least resistance. This relationship helps determine the trajectory and speed of charged particles in an electric field.
