what is the equation for thermal energy? 
mass x specific heat x change in temperature
what is the equation for work done? 
force x distance
what is the equation for kinetic energy? 
0.5 x mass x velocity^2
what is the equation for elastic potential? 
0.5 x spring constant x change in length^2
What is the equation for gravitational potential? 
mass x gravitational field strength x height
what is an isotonic solution? 
a solution that has the same solute and water concentration as inside of the cell. Meaning there is no change
what is a hypotonic solution? 
a solution that has a low solute concentration and high water concentration. may cause the cell to swell or burst.
when a cell is placed in a hypotonic environment… 
Water will enter the cell and it will swell
what is an hypertonic solution?
a solution that has a high solute concentration and a low water concentration. causes the cell to shrink or shrivel
what is specific heat capacity? 
The specific heat capacity (c) is the amount of
energy needed to increase the temperature of 1
kg of a substance by 1 °C.
what is conduction? 
Transfer of heat through direct contact between particles.
what is convection? 
Heat transfer through the movement of fluids.
what is radiation? 
Energy emitted in the form of electromagnetic waves or particles.
name two materials with low conductivity? 
Wood, plastic
name two materials with high conductivity 
Copper, Silver
