What is the correct calculation for voltage if the resistance is 3 ohms and the current is 4 amps? 3 + 4 = 7 volts 4 ÷ 3 = 1.33 volts 4 – 3 = 1 volt 3 × 4 = 12 volts

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
