Q

What is soluble?

A

When a solvent is able to dissolve more solute.

16
Q

What is insoluble?

A

When a solvent has so much solute that in can not dissolve anymore solute.

17
Q

What is unsaturated?

A

Not Able to dissolve more substance.

18
Q

What is saturated?

A

Able to dissolve more substance.

19
Q

What is the common measurement for volume of a liquid?

A

Millimetres mL

20
Q

What are 2 devices that can be used to measure volume?

A

beaker

flask

21
Q

Why must you read the volume of a liquid from the bottom of the meniscus?

A

The lowest point of the surface of the liquid is the most accurate.

22
Q

What is the mass of an object?

A

It is the number of particles in the object.

23
Q

What is mass usually measured in?

A

kilograms, kg
grams, g
milograms, mg

24
Q

What is weight?

A

Weight is a measurement depending on the force of gravity forced on the object.

25
Q

What is the difference between mass and weight?

A

The mass of an object or person doesn’t change based on his/her environment. A person’s or object’s weight changes depending on the amount of gravity acting on that person or object.

26
Q

What device is used to measure mass?

A

A scale.

27
Q

What is the scale used in the science lab called?

A

a triple beam balance

28
Q

Which objects could be measured using a triple beam balance?

A

pencil
iphone
paper
small container

29
Q

Which objects could not be measured using a triple beam balance?

A

big vase
person
large objects that have a large volume

30
Q

In what order of units should you measure when using the triple beam balance?

A

Measure in order from largest units to smallest units, then add them all up.

31
Q

How can you measure the mass of a solid?

A

Put the solid on the scale to find mass.

32
Q

How would you measure the mass of a liquid?

A
  1. Get mass of container with water.
  2. Get mass of empty container.
  3. Subtract mass of empty container from the full conatiner.
33
Q

How would you measure the volume of a liquid?
