Matter & Mass
This term describes how much matter (particles) an object has
What is mass?
The state of matter with particles that only vibrate in place.
What is a solid?
The correct tool for measuring a specific volume of a liquid.
What is a graduated cylinder?
A student bakes a cake and measures out 250g of flour, but forgets to tare the scale after placing the bowl on the scale. What happens? What is the result?
The measurement is incorrect - it also includes the mass of the bowl. Too little flour is poured out.
Water freezes at this temperature.
What is 0°C?
This term refers to how much space an object takes up.
What is volume?
The process where liquid turns into a gas.
What is evaporation OR what is boiling?
The unit "cm3" measures this property.
What is volume?
What is 8mL?
Water boils at this temperature.
What is 100°C?
What is the most typical unit used to measure mass in the science lab?
What are grams (g)?
The process where gas turns into a liquid, like water droplets on a cold bottle.
What is condensation?
What is the formula for finding the volume of a rectangular block, or something with "regular" straight edges?
What is length x width x height (LxWxH)?
Which tool should you use to heat liquids safely in the lab?
What is a hot plate?
The method of finding volume by placing an object in water is called this.
What is water displacement?
Mass and weight are not the same because weight depends on this.
What is gravity?
Water vapor turning directly into frost on a window is called this.
What is deposition?
The object that helps hold test tubes upright during experiments.
What is a test tube rack?
A mortar and pestle are used for this purpose.
What state of matter has particles that move freely and spread apart?
What is gas?
When measuring flour on a scale, what must you do before filling it up?
What is zero (tare) the scale OR subtract the mass of the container?
Name all six main phase changes of matter.
What are melting, freezing, evaporation, condensation, sublimation, and deposition?
Which tool is not for measuring volume:
- graduated cylinder
- overflow vessel
- scale
What is a scale?
When using a thermometer, why should the tip not touch the bottom of the beaker?
It gives an inaccurate reading of the liquid's temperature.
Identify the missing phase:
solid --> ? --> gas
What is a liquid?
