What else can I help you with?
What kind of shape volume and particles solid have?
solid have definite shape , definite volume and close together particles
What is the independent variable in an experiment that shows how the volume of gas changes with the temperature?
The independent variable in this experiment is the temperature. This is the variable that is manipulated or controlled by the researcher to observe its effect on the volume of gas.
How do you increase the volume of a gas without changing its particles?
You can increase the volume of a gas by increasing the pressure applied to it. By compressing the gas into a smaller space, the gas particles will occupy a larger volume due to the increased pressure. This does not change the number or type of particles present in the gas.
Can the particles in gas be compressed into smaller volume?
Yes, particles in a gas can be compressed into a smaller volume by reducing the space between them. This will increase the pressure of the gas as the particles are forced closer together.
If the pressure and number of particles are constant?
If the pressure and number of particles are constant, then according to Boyle's Law, the volume of the gas is inversely proportional to its pressure. This means that as the pressure increases, the volume decreases and vice versa, as long as the number of particles remains the same.
What was the conclusion of Rutherford's gold foil experiment in terms of an atom's mass and volume?
Rutherford found that when when he aimed alpha particles at a thin sheet of gold foil, that some of the particles were deflecteted and didn't go straight through the foil. The reason for this turned out the be that they ran into the nucleus. Most of the particles did go straight through, so Rutherford concluded that the atom was mostly empty space. He also concluded that the center of the atom contained the nucleus and had positively charged particles he called protons.
What does initial volume mean?
It refers to the volume of an object at the start of an experiment.
When using a pipet can you state the volume of the aliquot without calculating it?
Yes, the volume of the aliquot is typically indicated on the pipette itself. Most pipettes have volume markings along the side that allow you to easily set and dispense the desired volume without needing to calculate it.
What kind of shape volume and particles solid have?
solid have definite shape , definite volume and close together particles
What is the dependent variable in an experiment that shows how the volume of gas changes with the temperature?
The volume of gas
Is controlling variables a controlled experiment?
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.
What state will have the least number of particles in a certain volume?
The state with the least number of particles in a certain volume would be a gas, as the particles in a gas are more spread out and have more kinetic energy compared to particles in liquids or solids. This results in fewer particles occupying a specific volume in a gas compared to a liquid or solid.
What measurement best describes the result of a scientific experiment regarding volume?
The measurement that best describes the results of a scientific experiment regarding volume would be by using gallons.
What is the dependent variable in experiment that shows how the volume of gas changes with changes in temperature?
The volume of gas
What is the independent variable in an experiment that shows how the volume of gas changes with the temperature?
The independent variable in this experiment is the temperature. This is the variable that is manipulated or controlled by the researcher to observe its effect on the volume of gas.
How can you calculate the volume of H2O needed for a specific experiment?
To calculate the volume of water (H2O) needed for a specific experiment, you can use the formula: Volume Mass / Density. First, determine the mass of water required for the experiment. Then, find the density of water, which is approximately 1 gram per milliliter. Divide the mass by the density to calculate the volume of water needed.
Why did 50cm3 of soil and add 50cm3 of water not give total of 100cm3?
When soil particles are mixed with water, the soil particles occupy some volume, reducing the total volume of the mixture. This is known as the phenomenon of volume reduction due to the presence of solid particles in a liquid. Therefore, mixing 50cm3 of soil with 50cm3 of water will not result in a total volume of 100cm3 because the soil particles displace some of the water volume.
