The process of osmosis separates the mixture by changing the state of the water and making it a gas. Changing states is a form of physical change.
Answer:
True
Explanation:
These organisms are called unicellular, and can be different from multicellular organisms
The air particles in the bubble are forced to expand when we pull up on the plunger.
<h3><u>Explanation:</u></h3>
Pulling creates a large amount of volume , when the volume of the air bubble is increased, air particles inside the bubble tries to accumulate all of the volume by expanding the size of the bubble. Since according to Ideal gas law,
P V = n R T
where P = Pressure of the gas
V = Volume of the gas
n = No. of moles
R = Boltzmann's constant
T = Temperature
We can observe that pressure is inversely proportional to the volume of the gas. Therefore, when we pull up the plunger, the volume of the air bubble is increased and the pressure inside it is decreased.
Answer:
Atoms are composed of electrically charged particles and moving electric charges possess an associated magnetic field.
Explanation:
An atom is made up of electrons arranged in shells. Electrons are negatively charged. These charged particles produce an electric field which can interact with an external electric field to give information about atomic structure.
Similarly, a moving electron produces an associated magnetic field which can couple with an external magnetic field to give information about atomic structure.
Everything that can be measured is made up of matter and that is made up of small units called atoms.
