  • Q1
    Which statement about gas pressure and temperature is true?
    If the temperature of a fixed volume of gas is increased, the molecules of a gas move more slowly.
    The force that a gas exerts is parallel to the surface.
    Gas molecules all move around in the same direction.
    If the temperature of a fixed volume of a gas increases, the pressure it exerts increases.

  • Q2
    Which example is true about boiling and evaporation?
    Water boils at 1000°C.
    Evaporation occurs in a liquid at all temperatures, but a liquid only boils at its boiling point.
    A container of liquid left outside on a sunny day will boil.
    The liquid turns into a vapour.

  • Q3
    Which statement about density is true?
    Particles are closer together in the liquid state than the solid state, and this makes the liquid denser than the solid.
    An object will float in water if its density is less than that of water.
    Density is measured in kg/m2.
    A material usually has the smallest density when it is in a liquid state.

  • Q4
    Which statement about the particles in a solid, liquid, or gas is true?
    The potential energy of particles is caused by their velocity.
    The internal energy includes the kinetic energy of the motion of the whole substance.
    Internal energy is the sum of the kinetic energy and the potential energy of a substance.
    Energy stored by the particles in a solid is entirely kinetic.

  • Q9
    In which example would the pressure of a gas decrease?
    The air pressure in your lungs when your diaphragm moves down.
    Pressure of steam above boiling water in a saucepan when the lid is on.
    Gas pressure inside a sealed glass bottle left on the window sill in the sun.
    The pressure inside a tyre on a hot day compared to a cold day.

  • Q10
    Which statement about internal energy is correct?
    More energy is required to melt 100 kg of ice to liquid water than is needed to boil it from a liquid to a gas.
    Mass is not conserved in a physical change because atoms or molecules are not destroyed, just rearranged.
    The temperature of a solid doesn’t change when it is melting.
    A change in internal energy of an object can only result in a change in temperature.

  • Q11
    Look at the experimental setup. You notice that when you increase the pressure, the volume of the gas increases slightly. Choose the best explanation.
    Question Image
    When you exert a pressure on the gas you do work on it, which increases the mass of the gas molecules, so the gas expands.
    When you exert a pressure on the gas you do work on it, which increases the temperature, so the gas expands.
    When you exert a pressure on the gas you do work on it, which reduces the pressure, so the gas expands.
    When you exert a pressure on the gas you reduce the average speed of the gas molecules, so the gas expands.
