Density, Volume, Solids, Liquids and Gases Flashcards
1
Q
What is Density?
A
A measure of how much mass occupies a given volume.
2
Q
How do you calculate Density?
A
Density = mass / Volume
P = m / V
3
Q
What is the process of a Solid changing into a Liquid and Vice. Versa?
A
Sublimation
4
Q
What is the Internal Energy of a substance?
A
The Internal Energy is the energy stored by the particles of a substance.
5
Q
How can you increase the Internal Energy?
A
- Increasing the temperature
2. Changing the state
6
Q
How do you calculate the energy needed to change state?
A
Energy = mass x specific heat capacity x temp. change
Or
E = m x c x (temp. change)
7
Q
What is Pressure?
A
Pressure refers to when a continuous force is exerted onto a surface
8
Q
What is Boyle’s Law?
A
For a fixed mass of gas at a constant temperature, the pressure is inversely proportional to the volume.
