Answer
Increasing the pressure will raise the boiling point and lower the melting point, and decrease in pressure will lower the boiling point and raise the melting point of water and carbon tetrachloride.
Water is polar and has strong intermolecular hydrogen bonding; carbon tetrachloride is nonpolar. The boiling and melting points increase with the strength of intermolecular forces. When we vary the pressure, change of boiling point and melting point of carbon tetrachloride is more than that of water.
