The cards Question What does temperature measure? Tap to flip Answer How hot or cold an object is. Question In what unit do thermometers measure temperature? Tap to flip Answer Degrees Celsius (ºC). Question Where should your eye be when reading the scale on a glass thermometer? Tap to flip Answer Level with the top of the coloured liquid. Question At what temperature does pure ice melt? Tap to flip Answer 0ºC. Question At what temperature does pure water boil? Tap to flip Answer 100ºC. Question Water, sand and air have been left in the same room for a long time. How do their temperatures compare? Tap to flip Answer They are all the same: they are all at room temperature, whatever they are made of. Question What happens to the particles of a solid when it is heated? Tap to flip Answer They vibrate more quickly. Question What happens to the particles of a liquid when it is heated? Tap to flip Answer They move around more quickly. Question What happens to the separation of the particles when a solid or liquid is heated? Tap to flip Answer It increases: the particles get further apart. Question What happens to the volume of a solid or liquid when it is heated? Tap to flip Answer It increases: the solid or liquid expands. Question What does it mean for a substance to contract? Tap to flip Answer Its volume decreases. Question A small and a large ice cube are in the same freezer. Which one is colder? Tap to flip Answer Neither: they are at the same temperature. Question Hot water is mixed with cold water. How does the mixture's temperature compare with the two starting temperatures? Tap to flip Answer It is cooler than the hot water and warmer than the cold water. Question When hot and cold water are mixed, which starting temperature is the mixture's temperature closer to? Tap to flip Answer The temperature of the water there was more of. Question A cold object is placed in hot water. What happens to the motion of the particles in the object? Tap to flip Answer They move more quickly (while the water particles move more slowly). Question A hot object is placed in cold water. What happens to the motion of the water particles? Tap to flip Answer They move more quickly (while the particles in the object move more slowly). Question What does a hot drink do to the particles in the air around it? Tap to flip Answer It makes them move more quickly. Question Why do the particles of a hot drink slow down as it cools? Tap to flip Answer They transfer energy to the air particles. Question How does the temperature difference between a hot drink and the air affect how fast the drink cools? Tap to flip Answer The greater the difference, the faster it cools down. Question What is the cooling rate of an object? Tap to flip Answer How quickly its temperature falls. Question What is a cooling curve? Tap to flip Answer A line graph showing how a cooling object's temperature changes with time. Question Is the energy of a hot object destroyed as it cools? Tap to flip Answer No. The energy is dissipated (spread out), heating the surroundings. Question What is thermal conduction? Tap to flip Answer A change in temperature caused by particles passing on their motion through their bonds or by particle collisions. Question What is a thermal conductor? Tap to flip Answer A substance along which thermal conduction happens quickly. Question What is a thermal insulator? Tap to flip Answer A substance along which thermal conduction happens slowly. Question How quickly does the temperature along a thermal insulator rise when it is heated? Tap to flip Answer Very slowly. Question In a thermal conductor, what do vibrating particles do to the particles near them? Tap to flip Answer They quickly make those particles vibrate as well. Question During thermal conduction in a solid, do the particles move along the material? Tap to flip Answer No. The particles do not travel along the material; they pass on their vibrations. Question Why do materials that contain trapped air make good insulation? Tap to flip Answer Gases are very poor thermal conductors. Question What is insulation? Tap to flip Answer A layer of thermal insulator around an object to help keep its temperature the same. Question What does wrapping a cold object in a thermal insulator do? Tap to flip Answer It keeps the cold object cool (an insulator does not warm objects up). Question One ice cube is wrapped in aluminium foil and another in an insulator. Which melts first? Tap to flip Answer The one in aluminium foil (the conductor). Question In what directions do the particles in a solid, liquid or gas move? Tap to flip Answer In random directions. Question What must be transferred to an object to raise its temperature? Tap to flip Answer Energy. Question Two identical objects are at different temperatures. Which has more energy? Tap to flip Answer The one at the higher temperature. Question Two objects made of the same substance are at the same temperature. Which has more energy? Tap to flip Answer The one with more particles. Question What is a thermal energy store? Tap to flip Answer The energy a substance stores because of the random motion of its particles. Question What is heating? Tap to flip Answer Energy transferring from a high temperature to a low temperature. Question What is specific heat capacity? Tap to flip Answer The property of a material that determines how much energy must be transferred to it to raise its temperature. Question Do different substances need the same amount of heating to reach the same temperature? Tap to flip Answer No. Different substances need different amounts of heating. Question What does a higher specific heat capacity mean for the energy in 1 kg of a substance at a given temperature? Tap to flip Answer More energy is in its thermal store.

How this deck was checked On 2026-11-02, every card was compared with its source: the lessons of Oak National Academy, a public body funded by England's Department for Education that publishes lessons for the national curriculum. Because the cards come from those lessons, no second source was sought. The comparison was done automatically, not by a teacher, so a card can still be wrong. Flash Feed is not affiliated with any source named here.
