A beaker contains a mixture of sand and salt. A student adds water to dissolve the salt. Which processes can be used to separate out the sand and salt?
distillation to collect the sand and filtration to collect the salt
distillation to collect both the sand and the salt
filtration to collect both the sand and the salt
filtration to collect the sand and distillation to collect the salt

To separate the sand and salt mixture, the following processes can be used:
1. Filtration: Filtration can be used to separate the sand from the mixture. In this process, a filter paper or a sieve is used to separate the sand particles from the liquid. The sand remains on the filter paper or sieve, while the liquid (containing the salt) passes through.
2. Distillation: Distillation can be used to separate the salt from the water. In this process, the mixture is heated to convert the liquid (water) into vapor. The vapor is then cooled and collected, leaving behind the salt, which does not evaporate.
Therefore, the correct answer is: filtration to collect the sand and distillation to collect the salt.
