How to solve for joules
WebIn order to answer the question the first thing to do is divide the result by watts (remember that 1 watt is 1 joule per second): 9 x 10 16 J / 100 W = 9 x 10 14 seconds That's a lot of seconds, but how long is that in years? A year (365.25 days) is 31,557,600 seconds, so: 9 x 10 14 seconds / 31,557,600 seconds = 28,519,279 years WebHowever, there is a conversion factor between L·atm and the common unit of work, joules: 1 L·atm = 101.32 J. Using this conversion factor and the previous equation for work, we can calculate the work performed when a gas expands or contracts. ... We can start with the equation for q, but now different values are given, and we need to solve ...
