1. A The greater the salt content of water, the greater the conductivity of the water, and temperature correction is unnecessary because conductivity does not change with changes in temperature.
2. B The greater the salt content of water, the lower the conductivity of the water, and temperature correction is necessary because conductivity decreases with a rise in temperature.
3. C The greater the salt content of water, the lower the conductivity of the water, and temperature correction is necessary because conductivity increases with a rise in temperature.
4. D The greater the salt content of water, the greater the conductivity of the water, and temperature correction is necessary because conductivity increases with a rise in temperature.
