Observing Matter
Transparent
What do we use to measure mass?
A scale
If water is changing from a liquid to a solid, will energy be increasing or decreasing?
decreasing
What is density?
The amount of mass packed into a certain volume?
If I was measuring Ms. Malesku what unit of measurement would make the most sense to use?
Kg (kilograms)
What is the definition of a property?
A property is a characteristic that may help you identify or define an item
what is the definition of volume?
The amount of space something takes up.
What do the molecules in a gas look like?
Does a gas have more or less density than a liquid and solid?
If my mass was 60kg on earth, how much would my mass be on the moon?
60 kg. Our mass is always the same no matter what the gravitational pull is.
If I am observing something that has lustre, which of the 5 senses am I using to observe it?
Sight/Vision
when we are measuring mass, what exactly are we measuring?
The amount of matter in an object.
What is it called when something goes from a solid to a gas, skipping the liquid state.
Sublimation
Density = Mass divided by Volume
If I put a meatloaf into a bowl, why would it not take shape of the bowl like a liquid or a gas would?
Because the particles are in a fixed position because it is a solid.
What is the scientific name that we used for something you cannot see through at all?
Opaque
What items would I use to measure the volume of an irregular shaped object?
I would use a beaker or graduated cylinder full of water and measure using displacement.
name the real life example of deposition that we used in class.
Frost forming on a cold window without precipitation
Why do helium balloons float but balloons blown up by humans do not?
Helium is less dense than air
what temperature is the freezing point for water?
0 degrees celsius
Name 2 measurable properties we can use to describe matter.
Boiling point, melting point, freezing point, density, mass, or volume.
what is the unit of measurement that we use when we are writing down the volume of a regular object?
Cm3 (centimetres cubed)
what are the steps i would take to measure the mass of a liquid?
I would measure the empty beaker, then measure it with the liquid, then subtract the weight of the empty container from the total weight.
What steps would I take to find the density of a regular shaped solid?
measure the mass using a scale, then measure the volume using the LxWxH formula, then use the density formula: Density= Mass divided by Volume
If I am measuring the volume of an irregular object and the graduated cylinder starts at 45ml then moves up to 105 ml after putting the object in, what is the volume of my irregular object?
60ml
