What does the 6 mean in 6CO2?
There are 6 molecules of Carbon Dioxide (CO2)
What is it called when a gas turns into a liquid?
Condensation
An object has a mass of 200g and a volume of 50mL. Calculate it's density. Don't forget the formula and units!
D = M/V
D = 200g / 50mL
D = 4g/mL
What does the density of an object need to be in order to float in water?
Less than the water
Less than 1.0g/mL
What is the atomic number mean?
How many protons an atom has within it's nucleus
What is it called when 2 or more different atoms join together?
A compound
During a phase change, how does the temperature change?
It doesn't change, it remains the same
An object has a length, width and height of 5cm, 2cm and 10cm. It's mass is found to be 50g. What is it's density?
Volume = 5cm X 2cm X 10cm = 100cm3
D = M/V
D = 50g / 100cm3
D = 0.5 g/cm3
What is the atomic mass of an element?
It's protons and neutrons added together
