What does this mean? ?

collecting and analyzing data there are two types of observations: qualitative and quantitative.
qualitative observations use words to describe what is observed during the experiment. these
notes are kept in a journal or logbook. quantitative observations use numbers, such as calculations
and measurements that are recorded in data tables. scientists around the world use the same
system of measurement called the metric system. in your experiment the unit for volume is cubic
meters (m
3
). the unit for temperature is kelvin (k). create a data table for the quantitative data of
the lab.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
