What I will learn?

  • You would learn entire Solids, Liquids and Gases Course for IGCSE Physics (edexcel) certificate

Course Curriculum

Units–5.1 and 5.2
This lesson will mention all the units that are used throughout this section.

  • units–5.1 & 5.2
    00:00
  • Quiz 5.1 & 5.2

Density and pressure–5.3: Density = mass / volume
understand density as a ratio of mass and volume

Density and pressure–5.4: Investigate density of solids and liquids
We would learn how to work out density of solids and liquids in our laboratory

Density and Pressure–5.5: Understand Pressure = Force / Area

Density and Pressure–5.6: Understand Pressure at a point where fluid is at rest acts equally in all direction
At any stationary point in a fluid, the pressure is same from all directions

Density and Pressure–5.7 know and use the relationship for pressure difference: pressure difference = height × density × gravitational field strength p = h × ρ × g

Change of state–5.8P: explain why heating a system will change the energy stored within the system and raise its temperature or produce changes of state

Change of state–5.9P: what happens during change of states
5.9P describe the changes that occur when a solid melts to form a liquid, and when a liquid evaporates or boils to form a gas

Change of state–5.10P: Particles in all three states of matter
5.10P describe the arrangement and motion of particles in solids, liquids and gases

Change of state–5.11P: A graph that shows constant temperature during change of state

change of state–5.12P: know that specific heat capacity is the energy required to change the temperature of an object by one degree Celsius per kilogram of mass (J/kg °C)
5.12P know that specific heat capacity is the energy required to change the temperature of an object by one degree Celsius per kilogram of mass (J/kg °C)

5.13P use the equation: change in thermal energy = mass × specific heat capacity × change in temperature ΔQ = m × c × ΔT
5.13P use the equation: change in thermal energy = mass × specific heat capacity × change in temperature ΔQ = m × c × ΔT

Ideal Gas Molecules–5.15 explain how molecules in a gas have random motion and that they exert a force and hence a pressure on the walls of a container
5.15 explain how molecules in a gas have random motion and that they exert a force and hence a pressure on the walls of a container

Ideal Gas Molecules–5.16 & 5.17: Absolute Zero and Temperature Scale
5.16 understand why there is an absolute zero of temperature which is –273 °C. 5.17 describe the Kelvin scale of temperature and be able to convert between the Kelvin and Celsius scales

Ideal Gas Molecules–5.18: understand why an increase in temperature results in an increase in the average speed of gas molecules
5.18 understand why an increase in temperature results in an increase in the average speed of gas molecules

Ideal Gas Molecules–5.19: know that the Kelvin temperature of a gas is proportional to the average kinetic energy of its molecules
5.19 know that the Kelvin temperature of a gas is proportional to the average kinetic energy of its molecules

Ideal Gas Molecules–5.20,5.21 & 5.22: Relationship between P,V and Kelvin Temperature for a fixed mass of gas
5.20 explain, for a fixed amount of gas, the qualitative relationship between: • pressure and volume at constant temperature • pressure and Kelvin temperature at constant volume.
