Liquids are arranged in a regular pattern
What is the formula for density?
Density= mass / volume
Density= mass x volume
Density= volume / mass
Density= area x volume
Density= area / volume
Solids have ❌ density because the particles are packed closely together and they have a lot of ❌ for they volume except for ❌ which has ❌ density due to it’s ❌ structure (lots of air spaces).
Liquids have ❌ density because the particles are ❌ together, they have a lot of mass for their ❌
Gases have ❌ density because the particles are apart so gases only have a ❌ mass for their volume
The required practical to find the density for irregular objects is to find the mass then fill a ❌ can with water. After that we place the object into water, the water will be ❌ and the water flow out through the spout. We then measure the volume of water displaced using a measuring ❌.
Particles have kinetic chemical elastic( kinetic, chemical, elastic ) energy and potential electrical gravitational potential( potential, electrical, gravitational potential ) energy (intermolecular forces and chemical bonds)
When a solid can turn directly into a gas it is called . An example of this carbon dioxide at room temperature.
Evaporation is when a liquid turns into a gas fully
Why does the temperature stay constant in changes of state?
The energy is being used to break the forces of attraction
The energy has dissipated
The specific ❌ heat of a substance is the amount of energy required to change state of one ❌ of the substance with no change in temperature
Specific latent heat of fusion vaporisation( fusion, vaporisation ) is the energy required to change 1 kg of a substance from a solid liquid gas( solid, liquid, gas ) to a liquid solid gas( liquid, solid, gas ) with no change in temperature
Specific latent heat of ❌ is the amount of energy required to change 1 kg of a substance fro a ❌ to a ❌ with no change in temperature
Gas pressure is due to the particles colliding with the walls of the container that the gas is held in.
