What is Brownian motion?
100
This is greatest in solids.
Which state has the greatest order.
100
A measurement made universally true for a material, rather than an abject, by taking into account the mass in question.
What does 'specific' mean?
200
The energy required, per kilogram, to change the state of a substance from liquid to gas, while at constant temperature.
What is the latent heat of vapourisation?
200
The energy difference between points B and C.
What is the means of calculating the latent heat of fusion from Figure 1?
200
Collisions between the air and smoke particles, causing them to change direction randomly.
What causes Brownian motion?
200
A substance between its melting and boiling points.
What is a liquid?
200
A scale measured in Kelvin, determined by the triple point of water and absolute zero.
What is the absolute temperature scale?
300
The form of energy change being described by a substance's latent heat.
What is potential energy?
300
The inverse of the gradient of a Temperature vs Energy supplied graph for a 1kg object.
What is a way to use a graph to determine a substance's specific heat capacity?
300
Supplying a constant rate of energy to a substance and measuring the temperature change caused.
What is a method to determine the specific heat capacity of a substance?
300
A substance of internal energy significantly greater than its latent heat of fusion and vapourisation combined.
What is a gas?
300
If two systems are in thermal equilibrium with a third system, then they must also be in thermal equilibrium with each other.
What is the zeroth law of thermodynammics?
400
The symbol representing the energy required to change the temperature of a substance by 1K.
What is'c'?
400
The energy change for an object of mass 3kg, specific heat capacity 4200 J/kgK which goes from 300K to 321K given in kiloJoules.
What is 0.26 kJ?
400
Little or no movement, vibrating about their position in a rigid lattice.
What is the motion of particles in a solid?
400
Pressure and temperature.
What parameters determine the position of a substance's triple point?
500
The total sum of kinetic and potential energies of the molecules in a substance.
What is internal energy?
500
The Latent heat of fusion for an object of 5.5 kg, which requires 127kJ to change from solid to liquid.
What is 23 kJ/kgK?
500
The point at which the internal energy being lost by the substance is caused by increasing order and decreasing spacing rather than changes to the motion.
What is the flat point on a substances cooling curve?
500
Their motion, order, spacing and the forces acting between them.
What differences are there between the particles in solids, liquids and gases?
500
