(2) increases
(3) remains the same
As the temperature of liquid increases, its vapor pressure increases. Therefore, option (2) is correct.
Vapour pressure can be defined as the pressure exerted by a vapor with its condensed phases in a closed system at a given temperature. The equilibrium vapor pressure is also served as an indicator of the rate of evaporation of a liquid.
A material that has a high vapor pressure at normal temperatures is commonly referred to as a volatile material. The pressure exhibited by the molecules of the gas above a liquid surface is called vapor pressure.
The temperature and the vapor pressure of liquid are directly related to each other. If the temperature of the liquid increases, more gasmolecules have the energy to escape from the surface of the liquid.
Therefore, the vapor pressure increases with an increase in the temperature of the liquid.

Answer: you cannot find its new volume by using these known values and Boyle's law because the temperature does not remain constant.
Explanation:
Boyle's law states that the volume of a fixed amount of gas, at a constant temperature, varies inversely with the pressure.
So, it is a condition that the temperature does not change.
For the wheater ballon case, as it travels through the atmosphere, the temperature at different altitudes will be different.
So, you might use other equation of states, such as the combined law, which does deal with changes in the three variables: volume, pressure, and temperature.
The mathematical formulation of Boyle's law is:
pV = constanjt ⇒ p₁ V₁ = p₂ V₂, at constant T.
The mathematical formulation of the combined law of gases is:
pV/T = constant ⇒ p₁ V₁ / T₁ = p₂ V₂ / T₂, for a fixed amount of gas, then it might work for the weather ballon (if you know the initial and end temperatures).
You cannot find the new volume by using initial volume of the weather balloon and air pressure ai its initial and final altitudes and Boyle’s law because the given values are not the same. Boyle’s law holds for the pressure and volume of the GAS at constant temperature. Here you are given the air pressure outside the weather balloon not the inside of the balloon. They have different gases and so it would not apply.
In determining the empirical formula of a compound, you must convert the mass of each element to moles. Since the given mass for this problem is 0.212 grams of Magnesium and 0.140 grams of Oxygen, just divide the mass by the molar mass of Magnesium (24.305 g/mol) and Oxygen (16 g/mol).You’ll get 0.00872 moles of Magnesium and 0.00875 moles of Oxygen. You then divide the each mole value with the smallest calculated number of moles which is 0.00872. You will get an empirical formula of MgO.
