SCRIPT 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◍ sublimating.
Answer: solid to gas or gas to solid
◍ Conduction.
Answer: The direct transfer of heat from one substance to another substance
that it is touching.
◍ specific heat capacity.
Answer: the energy required to raise the temperature of one gram of a
substance by one degree Celsius
◍ gravitional potential energy.
Answer: potential energy that depends on the height of an object
◍ What is acceleration?.
Answer: The rate of change of velocity; the amount of velocity changes per
unit time
◍ background radiation.
Answer: nuclear radiation that occurs naturally in the environment
◍ half-life.
Answer: the period of time in which half of a radioactive substance decays
◍ energy transfer.
, Answer: power x time
◍ boiling.
Answer: liquid to gas
◍ What is the limit of proportionality?.
Answer: The point beyond which Hooks Law is no longer true when
stretching a material
◍ elastic potential energy.
Answer: the energy of stretched or compressed objects
◍ Infra red radiation.
Answer: Electromagnetic waves of heat energy.
◍ What is an electromagnet?.
Answer: A solenoid with an iron core
◍ What is a non-contact force?.
Answer: Non-contact forces are forces that act between two objects that are
not physically touching each other
◍ Plum Pudding Model.
Answer: The model of an atom in which there is a positively charged ball
with electrons dotted through it.
◍ ion.
Answer: atom that has a positive or negative charge
◍ carbon dating.
Answer: a scientific method used to determine the age of an artifact
◍ What is the unit for force?.
Answer: Newton (N)
◍ sinking.
Answer: weight > upthrust
◍ specific latent heat of vaporisation.
Answer: the energy needed to change a unit mass from the liquid to the
, vapour phase at constant temperature
◍ isotopes.
Answer: atoms of the same element that have different numbers of neutrons
◍ In Fleming's Left-Hand rule what does the first finger direction represent?.
Answer: The direction of the field
◍ What is the unit of acceleration?.
Answer: Metres per second squared (m/s2)
◍ Convection.
Answer: The transfer of thermal energy by the circulation or movement of a
liquid or gas
◍ Sources of background radiation.
Answer: Radon gas, cosmic rays, rocks, building materials, medical x-rays,
food, nuclear industry
◍ greenhouse effect.
Answer: CO2 and other greenhouse gases in the atmosphere absorb long
wavelength radiation radiated from the Earth's surface and prevent it
escaping.
◍ Reduce heat loss from homes.
Answer: - loft insulation (fibre glass is a good insulator)- cavity wall
insulation (foam prevents convection currents)- aluminum foil behind
radiator (reflects radiation)- double glazing (vacuum slows conduction and
radiation)
◍ What is Newton's Third Law of motion?.
Answer: When a contact force acts between two objects, both objects
experience the same size force, but in opposite directions
◍ sound energy.
Answer: Energy caused by an object's vibrations
◍ What does a horizontal line on a velocity-time graph represent?.
Answer: An object moving at constant velocity
