Which samples will heat up faster?
circle
one
100 g (least massive) 200 g (most massive) No Difference
Explain your reasoning: The 100g one will heat up faster because there is less so it wont
take as long compared to the 200g
Which samples will heat up faster?
circle
one
Water Wet Sand Dry Sand No Difference
Explain your reasoning:The dry sand will heat up faster because the intermolecular force
of attration is less in solids so that makes the dry sand easier to heat up because of the
lack of liquid
