BMAT Exam Questions and Answers
(Latest update 2024) 200+ Questions
What factors affect the magnitude of an induced voltage? - Correct Answer
✅- the rate at which the wire cuts the magnetic field lines
-- e.g.the magnet spins at a greater rate meaning more field lines are cut per
second
-- a stronger magnet is used meaning there are more magnetic field lines
- the rate at which the magnetic filed through a conductor changes
-- e.g. the ac frequency in coil A is increased
-- e.g. the ac amplitude in coil A is increased
- number of turns in the coil is increased

What is the role of red blood cells in the blood? - Correct Answer ✅Carry
oxygen
What is the role of white blood cells in the blood? - Correct Answer
✅antibody production and phagocytis
What is the role of platelets in the blood? - Correct Answer ✅Blood clotting
What are the roles of plasma in the blood? - Correct Answer ✅- transport
of blood components and other dissolved substances and other dissolved
substances including hormones, antibodies, urea and carbon dioxide
- distribution of heat
What are the properties of transition metals? - Correct Answer ✅they are
able to form stable ions in different oxidation states b. they often form
coloured compoundsc. they are often used as catalysts (as ions or atoms)
Test for oxygen - Correct Answer ✅Relights a glowing splint
Test for chlorine - Correct Answer ✅damp blue litmus paper turns red and
is the bleached (paper turns white)
Flame test - Li - Correct Answer ✅crimson red

Flame test - Cu - Correct Answer ✅green
How do you test for the presence of water? - Correct Answer ✅- Add
anhydrous copper(II) sulfate
- Results in a colour change from white to blue
How can two insulators become charged? - Correct Answer ✅by friction
- when two insulators move relative to each other, they can become
electrically charged
- one will become positively charged and the other negatively charged
- e.g plastic rubbed by a duster, hair combed, fuel moving through a pipe
and an aeroplane moving through the air
Can conductors become charged by friction? - Correct Answer ✅Yes, if
they are insulated from their surroundings, otherwise the charge will leak
away
How can a neutral object become charged by induction? - Correct Answer
✅Much like when a unmagnetised piece of iron becomes magnetised when
it moves near to a magnet, a neutral object can become charged when
placed near to a charged object
How can an object charged by induction become permanently charged? -
Correct Answer ✅If it is momentarily earthed, allowing the charge at one
end to leak away
How does an object become charged in terms of particles? - Correct
Answer ✅- when two objects are rubbed together, there is a transfer of
electrons
, BMAT Exam Questions and Answers
(Latest update 2024) 200+ Questions
- if an object gains electrons, it becomes negatively charged
- if an object loses electrons, it becomes positively charged
ELECTROSTATIC CHARGE IS ALWAYS CAUSED BY ELECTRONS
- which way the electrons move and so how each material becomes charged
depends on how strongly the atoms attract electrons
What are uses of electrostatic charging by friction? - Correct Answer ✅-
photocopying
- laser printing
- electrostatic air cleaning
What are risks of electrostatic charging by friction? - Correct Answer ✅-
can result in sparks
-- occur when air between two objects becomes ionised and starts
conducting
- two charged objects with air between them can discharge a spark when the
charge becomes large enough or the distance between them becomes small
enough
How can the risks associated with electrostatic charging by friction be
eliminated? - Correct Answer ✅earthing
- by both being connected by a wire or one object being connected by a wire
to the earth
-- means that electrostatic charging cannot take place so the risk is averted
wires crossing - Correct Answer ✅
wires connected - Correct Answer ✅
