It should be observed in Part 2 of the experiment that when the temperature of the gas sample in Celsius degrees has a value of zero, the volume of gas in the sample has a value greater than zero. Explain why it would not be correct to say that at a constant pressure and for a fixed amount of gas, the volume occupied by a gas is directly proportional to the Celsius temperature.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
