A net force of 15 N is exerted on a textbook to cause it to accelerate at a rate of 5 m/s2. Determine the mass of the textbook

The freezing and boiling point of a substance changes as the air pressure around it changes. for example, at a lower air pressure (higher altitude) it is easier for water molecules to escape from liquid into the air. in a high altitude city such as denver, colorado compared to a sea-level city such as houston, texas, water
