Question

A scientist claims that 'The solubility of Compound Z is strictly dependent on temperature and is unaffected by pressure.' Do the results of Experiment 3 support this claim?

Accepted Answer

Yes; increasing the pressure from 1 to 5 atm at a constant temperature resulted in negligible changes in solubility.

Answer

Yes; increasing the temperature resulted in a decrease in solubility.

Answer

No; increasing the pressure caused a significant increase in the solubility of Compound Z.

Answer

No; the solubility remained constant regardless of temperature changes.

Temperature (°C)	Pressure (atm)	Solubility (g/100g H2O)
20	1	15.2
20	5	15.1
40	1	28.4
40	5	28.5
60	1	42.9
