What are element, compounds and mixtures?
ELEMETS- 1 type of atom
COMPOUNDS- 2 or more types of elements that ARE chemically bonded together
MIXTURES- 2 or more types of elements that are NOT chemically bonded together.
Where are elements found ?
The Periodic Table
What is current?
Current is the rate of flow of charge.
What is voltage? Voltage is potential difference across 2 points in a circuit Voltage is potential different Voltage.
Potential
Potential difference across two points in a circuit.
What is resistance?
Resistance is how difficult it is for current to flow around a conductor.
What's two electrical components stated here
What are conductors?
Conductors are materials that let current flow through it easily.
What are insulators? Insulators are a material which do not select currents flow through it.
Insulators are a material that doesn't let current flow through its easily.
What is static electricity?
Static electricity is when you rub 2 insulators together and the build up causes electrons to transfer from one material to another
What is a series circuit??
Series circuit has all the components in one loop connected by wires, so there is only one route for current to flow.
What is a parallel circuit?
A parallel circuit has components on separate branches, so the current can take different routes around the circuit..
What's order is human and plant organisms?
Cells , Tissues , Organ , Organ System , Organism
What is the diffusion?
Deffusion is the movement of particles from a high concentration to a low concentration
What is concentration How much material can be found in a gift? How much material can be found in a given volume? How how much richer will come
Concentration how much material can you found in a given volume
What happens during inhalation
DURING INHALATION:
Air is drawn in
Intacostal muscles contract
Diaphragm contracts
Chest expads
What's happens during exhalation
During Exhalation:
Air is blown out
Intacostal muscles relaxes
Diaphragm relaxes
Chest contracts
