How are the particles arranged in a solid?

Packed closely in a fixed regular pattern, vibrating

What causes the pressure of a gas?

Particles colliding with the walls of the container

The average kinetic energy of the particles

The particles move faster and hit the walls harder and more often

The energy to raise the temperature of 1 kg by 1 degree Celsius

Energy equals specific heat capacity times mass times temperature change

The energy to change the state of 1 kg without a temperature change

The energy is used to break bonds rather than raise the kinetic energy of the particles

Energy equals mass times specific latent heat

Gas particles are far apart with lots of space between them
