Answer:
The volume increases by 10.3 mL.
Explanation:
This is not an easy question to answer, because water expands at different rates depending on the temperature.
However, we can use the known densities of water at these temperatures.
(a) Calculate the mass of 1 L of water at 20 °C.
The density of water at 20 °C is 0.998 20 g/mL.
[tex]\text{Mass} = \text{1000 mL} \times \frac{\text{0.998 20 g}}{\text{1 mL}} = \text{998.20 g}[/tex]
(b) Calculate the volume at 50 °C.
The density of water at 50 °C is 0.988 03 g/mL.
[tex]\text{Volume} = \text{998.20 g} \times \frac{\text{1 mL}}{\text{0.988 03 g}} = \text{1010.3 mL}[/tex]
∴ The volume increases by 10.3 mL.
