Mass & Volume Questions
What is Matter?
Something that has mass and volume
Give characteristics of a liquid:
(hint, 2)
Liquids have the following characteristics:
Physical change? Give an example.
The matter changes but not the physical properties, example an ice cube melting.
Who created the periodic table?
Mendeleev
Give two characteristics of metals
-shiny luster
-good conductors of heat and electricity
-easily bent
-Mostly solids at room temperature
What is mass?
The measure of how much matter an object has
Give characteristics of a solid
Solids are defined by the following characteristics:
Product?
A product is a substance that is formed as the result of a chemical reaction.
Elements in groups share __________.
Properties
What is the name of the most stable metals?
Noble gases
What is the difference between mass and weight?
Whereas mass measures the amount of matter in an object, weight measures the force of gravity acting on an object.
Give characteristics of a gas
Gases have the following characteristics:
Law of conservation of energy?
Energy is neither created nor destroyed
Give an example of a metal
Zinc, iron, etc.
Give two characteristics of alkali metals
-extremely reactive
What is volume? Give an example
Volume is a measure of the amount of space an object takes up. An example would be the amount of space or volume that fills up a water bottle.
How many states of matter are there?
four! Liquid, gas, solid, and very rarely plasma
Kinetic energy?
Energy an object presents due to motion.
Give an example of a metalloid, what is it?
Boron, other answers work too.
Somewhat shiny and semiconductors.
Rare earth metals are very _________.
Reactive
Give an example, explaining the difference between weight and mass.
A good one would be comparing the difference of weight on the earth vs the moon. The mass stays the same whereas the weight decreases on the moon due to less gravitational force.
What is Plasma?
Reactant
A substance that takes a part in and undergoes change during a reaction.
What halogen is the most reactive?
Fluorine
Give an example of transition metals. Name some of their characteristics
Hard metals
shiny luster
Good conductors
Not very reactive
ex, gold, iron, copper
