Question 8

An alcohol thermometer contains a small quantity of ethanol.

a.

The mass of the ethanol in the thermometer is 16 g16\text{ g}16 g.

Calculate the weight of the ethanol. (Take g=10 N/kg)(\text{Take } g = 10\text{ N/kg})(Take g=10 N/kg)

[2]
b.

The 16 g16\text{ g}16 g of ethanol has a volume of 20 cm320\text{ cm}^320 cm3. Calculate the density of ethanol.

[2]
c.

The ethanol in the thermometer expands when its temperature rises.

State what happens to the mass of the ethanol when its temperature rises. Choose from:

  • mass decreases
  • mass stays the same
  • mass increases
[1]
d.

State what happens to the density of the ethanol when its temperature rises. Choose from:

  • density decreases
  • density stays the same
  • density increases
