A
expansion of air in the flask
B
expansion of the glass flask
C
expansion of the glass tube
D
expansion of the mercury

Which row is correct?
the one which
expands most
the reason
the gas
molecules in the gas each expand
more than the solid molecules
the gas
the molecules in the solid
are held strongly together
the solid
molecules in the solid each expand
more than the gas molecules
the solid
all the molecules in the gas are
separate from one another
Question 15
[Maximum number: 1]
A model thermometer consists of a flask of coloured water and a stopper with a glass tube passing through it, as shown.
The model thermometer can be changed in one of two ways.
- The flask can be replaced with a larger one full of coloured water.
- The glass tube can be replaced with one with a larger internal diameter.
Which statement is correct?
A
Only using a larger flask increases the sensitivity.
B
Only using a wider tube increases the sensitivity.
C
Using a larger flask increases the sensitivity and using a wider tube increases the sensitivity.
D
Neither using a larger flask nor using a wider tube increases the sensitivity.
Question 16
[Maximum number: 1]

C
increase the length of the tube and stem
D
increase the thickness of the glass in the glass bulb
