1What are the properties of a solid?
- The particles vibrate around a fixed position
- They have a fixed shape
- Have a fixed volume; cannot be compressed
- Arranged in rows
2What are the properties of a liquid?
- Particles packed tight but can move over each other
- Can take their container’s shape
- Can’t be compressed
3What are the properties of a gas?
- Particles move freely
- Take their container’s shape
- No fixed volume; can be compressed
- Random arrangement
4What is density?
a measurement of the amount of substance per unit volume
5What is heat?
the total thermal or kinetic energy of particles; measured in Joules
6What is temperature?
a measure of the average kinetic energy of particles in a substance; measured in degrees Celsuis
7What is internal energy?
total kinetic and potential energy of all particles in an object
8What is specific heat capacity?
the amount of energy needed to raise the temperature of 1kg of an substance by 1 degree
9What is specific latent heat?
the amount of energy needed to change the state of 1kg of an object completely without changing the temperature (symbol L, unit J/kg)
10What is specific latent heat of fusion?
freezing or melting per kg of a substance
11What is specific latent heat of vaporisation?
condensation or evaporation per kg of a substance
