Heat transfer
Term that describes heat transfer that occurs through a vacuum (space without particles)
Radiation
Three states of matter
Solid, liquid, and gas
A list of elements are found on the....
The periodic table of elements
State two types of specialised animal cells.
Nerve, muscle, sperm, egg (ovum), red blood cell, white blood cell
Equipment worn to protect eyes
Safety glasses/goggles
Term that describes the transfer of energy by heating up, decreasing in density, then being replaced by more dense particles. This forms a current/cycle of heating.
Convection
Particles move rapidly in this state of matter
Gas
Term that describes a pure substance is made of two or more elements chemically bonded together.
Compound
Organelle that contains DNA and controls the function of the cell
Nucleus
Equipment used to measure the volume of a liquid?
Measuring cylinder
The average thermal (heat) energy within a system
Temperature
This term describes particles of a liquid and a gas
Fluid
An impure substance that is made of more than one type of particle not chemically bonded together.
Mixture
State a type of specialised plant cell
Root hair cell, palisade cell, guard cell
Independent, dependent, and control
A property that will absorb more thermal energy through radiation
Dark/Dull colours
How can you increase the pressure inside a container?
Heat the container
Decrease the volume of the container
Add more particles
C6H12O6 is the chemical formula for glucose.
How many elements are there in a molecule of glucose?
3
Site for respiration which produces energy. Known as the "powerhouse of the cell".
Mitochondria
Stretched length - original length = extension
Why do metal chairs feel cold in winter but hot in the summer?
They are good conductors. Transfer heat to you in the summer and absorb heat from you in the winter.
How does cooling the gas inside a container decrease the pressure?
Particles move slower causing less collisions with the walls of the container/less force
Chemical formula for Hydrochloric acid
HCl
Amniotic fluid
