Section 2: Chemistry and Matter

Chemistry and Matter


1.	Which of the following releases matter? Need a Hint?
		A)	engaging a car exhaust system
		B)	picking up iron filings with a magnet
		C)	turbines spinning in a power plant
		D)	turning on an electric hot plate


2.	Why can an object's weight vary with location but its mass cannot? Need a Hint?
		A)	Determinations of mass account for varying gravitational pulls in different locations.
		B)	Mass is a measure of the amount of matter in an object; weight is not.
		C)	Systems of measurement vary with location.
		D)	Weight is a measure of both mass and the effect of Earth's gravitational pull on the matter. Mass measures only the amount of matter.


3.	Anything that has mass and takes up space is _________. Need a Hint?
		A)	matter
		B)	volume
		C)	pressure
		D)	weight


4.	What is the measurement of matter whose value depends on the force of gravity? Need a Hint?
		A)	mass
		B)	volume
		C)	energy
		D)	weight

		A)	analytical chemistry
		B)	organic chemistry
		C)	physical chemistry
		D)	inorganic chemistry


6.	Chemists who study the chemistry of living organisms work in the field of ______________. Need a Hint?
		A)	analytical chemistry
