What method of separating solutions would be used to separate salt from a saltwater solution?
Evaporation
Students in Ms. Hargrove’s class were instructed to mix sugar and sand in water. Before they started, they needed to heat the water to 90 degrees Celsius. Then, they added the sand and sugar and stirred for ten minutes. They observed what happened and documented it in their journals. Ms. Hargrove then asked the students to separate the sand and sugar from the water. Which of the following steps should the student take?
a. Filter out the sugar and boil the water
b. Let the solution stand for ten minutes to let the sugar and sand settle
c. Use a magnet to separate them
d. Filter out the sand and boil the water
d. Filter out the sand and boil the water
What is density?
a. How heavy or light an object is in relation to its size.
b. The amount of matter in an object.
c. How well electric current moves through an object.
a. How heavy or light an object is in relation to its size.
Which physical properties best describe a gas?
a. Definite volume, definite shape
b. Definite volume, no definite shape
c. No definite volume, no definite shape
c. No definite volume, no definite shape
