Why is energy needed to move the particles across the plasma membrane?
Energy is only necessary for diffusion if the particles are being moved across the membrane against the gradient. ATP is necessary for this active transport as particles are moved from low concentrations to higher concentrations across the membrane. This is because passive transport, which does not use energy, only works to move particles down their concentration gradient. Ex. Such active transport is used in neuron cells to have a different charge inside and outside of the cell so that it can relay electric signals.
How particles moved?
yes
Why should it take significantly more energy to move a beam of alpha particles than a beam of beta minus?
Alpha particles have a higher mass and charge compared to beta minus particles, leading to stronger electromagnetic interactions with surrounding particles. As a result, the alpha particles experience more resistance and require more energy to be moved through a medium compared to beta minus particles.
Do particles of liquid only moved when shaken?
No, particles of a liquid are always in motion due to thermal energy, even when they are not shaken. This movement occurs as they collide with one another, allowing liquids to flow and take the shape of their container. Shaking a liquid increases the energy and speed of the particles, enhancing their movement and mixing.
How did the particles inside the balloon move?
The particles inside the balloon moved randomly due to the kinetic energy they possess. The temperature of the gas inside the balloon affects the speed at which the particles move. When the gas inside the balloon is heated, the particles move faster and spread out, causing the balloon to expand.
Can particles be moved?
Yes, particles can be moved by various forces such as gravity, electromagnetic forces, and mechanical forces. These forces can cause particles to change position or be displaced from their original location.
What moves particles from low consentration to high consentration?
Active transport is the mechanism by which particles are moved from areas of lower concentration to areas of higher concentration in a cell. This process requires energy to pump the particles across the cell membrane against their concentration gradient.
What is the energy of moving particles in a subatnce?
The energy moving in particles in a substance is thermal energy
________ energy is the total kinetic and potential energy of the particles in an object.?
In microscopic particles it's called internal energy. In macroscopic particles it's called thermodynamic energy.
What is the kinetic energy of a substance and the kinetic energy of its particles?
The kinetic energy of a substance is the total energy associated with the movement of all its particles. The kinetic energy of individual particles is the energy due to their motion. The two are related, as the total kinetic energy of a substance is the sum of the kinetic energies of all its particles.
Which answer lists the substances in order from greatest energy of particles to least energy of particles?
The order from greatest energy of particles to least energy of particles is: Plasma > Gas > Liquid > Solid.
What is moved in science?
In science, objects, particles, or substances can be moved from one place to another by applying a force or energy. This movement can be used to study the behavior of matter and to understand laws of motion and energy transfer. Transporting materials allows scientists to conduct experiments, analyze data, and make observations that contribute to scientific knowledge.
