An object has a mass of 15g a volume of 20cm3 and a density of 0.75 g / cm3. Will this object sink or float when placed in water & WHY??
0.75g/cm3 is LESS dense than water at room temperature (1.0g/mL). Therefore, this object will float when placed in water.

True or False - if you write units at the top of the column in your data table, you must also write them next to each measurement you record in the data table...
False

What is surface tension?
The force of cohesive water molecules - strong attraction/bond - keep water molecules together and sometimes objects can't pass through

What do mass & weight have in common?
What factor/variable makes them different?
Both mass & weight are measurements telling you how much matter there is in an object or substance. However, weight also has the force of gravity on the object and can change with location. Mass will not change with location.

How do you find the mass of a liquid?
Subtract the mass of the empty container from the mass of the liquid and container

How does displacement work in relation to buoyancy?
The object moves the water when it enters the water. Water will then push upward against the object with force equal to the weight of the water that’s being displaced.
