Unformatted text preview: How can 1295 be written in scientific notation? ___________________________ Temperature: When using temperature in calculations always use Kelvins!!! Temperature in degrees Celsius is equal to Kelvins plus 273.15. 38 degrees C= K 200K= degrees C Matter is anything that takes up volume and has mass. Water, gases, elements… etc Unit Conversions: Look at table 1.5 in book! To go from meters to kilometers… 3.4m x 1Km/1000m = .0034 SN:____________________ 2.5 Km= m Physical and Chemical Properties: Physical properties do not change the element or compound. Chemical processes undergo reactions. Name whether the following are physical or chemical processes. Melting Freezing Converting element to compund Boiling Converting compound to compound crushing Picture from http://grahamt48192.tripod.com/generalchemistrychem1615tgraham/id14.html...
