Mass

~What is the difference between mass and weight?

-Mass:the amount of matter in something

-Weight: depends on gravity or the force of attraction between two objects

Example: If we went into outer space, would we still have mass?

Answer:Yes, because we are still made up of moleculesWhat would we weigh?

Answer: Nothing, because there is no gravity

~What do scientists use to measure mass?Answer: A balance

~What is the base unit in the metric system used to measure mass?

Answer: grams

Length~Base unit: meter

Look at a ruler: The lines with numbers are centimeters. The smaller unnumbered lines are millimeters. (10 between each cm)

Another system of measuring temperature is the __________ system. This is also in the _____________ System. 0o K is the theoretical temperature at which all motion stops. This iscalled _______________ _______________. It is equal to __________ oC. Therefore the freezing point of waterin Kelvin is _______K and the boiling point of water is _____K.
