changes of matter (density, shc etc.)

Question 1

what is the equation for heat energy?

Answer 1

heat energy=mass x specific heat capacity x change in temperature

AKA

Q=mc(change in)T

Question 2

what is the equation for density?

Answer 2

density=mass/volume

Question 3

what is the equation for pressure?

Answer 3

pressure=force/area

AKA

P=F/A

Question 4

what would a flat line represent on a graph showing state changes and temp increases?

Answer 4

a flat line represents a change of state

Question 5

why does temperature not increase during a change of state?

Answer 5

all the energy is used up on the state change and their is no left over heat energy to increase the temperature
