2(a)[1]
23 (°C)
2(b)[1]
s, °C
2(c)(i)[2]
view scale / value / water level at right angles / perpendicularly
to bottom of meniscus
2(c)(ii)[1]
measuring cylinder can only be read to nearest 1 or 2 cm3.
OR
to nearest cm3 means you are measuring the volume to 3 significant figures (which is sufficient)
2(d)(i)[2]
R1 = 0.15
with unit °C / s
2(d)(ii)[1]
R2 = 0.05
2(e)[1]
yes;
with numbers given, starting from a higher temperature the cooling rate is 0.15 °C / s but starting from a lower temperature the cooling rate is 0.05 °C / s
2(f)[2]
lid
insulation
