Internal Energy and Particle Motion | GCSE Physics
Internal energy is the total energy stored by the particles that make up a system.
Which two types of energy make up internal energy?
What is Internal Energy and Particle Motion | GCSE Physics?
"The total kinetic and potential energy of all the particles that make up a system."
What is the formula for density?
Why does a crisp packet puff up when taken on an airplane flight?
Calculate the pressure at a depth of 2m in water (density = 1000 kg/m³, g = 9.8 N/kg).
Specific heat capacity is the energy needed to raise 1kg of a substance by ____.
Particle Energy
Internal energy = total kinetic energy + total potential energy of particles.
Heating increases the energy stored within the system.
This either raises the temperature or changes the state.
Particles in a gas move randomly at high speeds.
Definition Check: Potential energy in particles comes from their bonds and positions; kinetic comes from their movement/vibration.
