How does energy transform matter? Flashcards
1
Q
What is density
A
Mass per unit volume
2
Q
Density formula
A
DMV Density=Mass(KG)/Volume(m^3)
3
Q
What is specific heat capacity?
A
The energy required to raise the temperature of 1kg of any substance by 1 degree celcius.
4
Q
What is the specific latent heat of a substance?
A
The energy required to change state of a material is known as latent heat. The energy required to change the state of 1kg of that material is known as specific latent heat
5
Q
Specific latent heat formula
A
LHM Specific latent heat= Heat energy/Mass
6
Q
Change in energy formula
A
Change in Energy (J)= mass(KG) x specific heat capacity(J/KGoC) x change in temperature (oC)
7
Q
Work formula
A
PWT Work=Power x Time
8
Q
Kinetic energy formula
A
Kinetic energy= 1/2 x mass x (velocity^2)
