Geoff23 Posted April 25, 2007 Report Share Posted April 25, 2007 Hi, I am stuck on this question and would really appreciate some pointers on how to solve it, The specific heat capacity of the lava is 1600 J kg^-1 oC^1. when all the erupted lava cools from the eruption temperature of 1050 degrees Celsius to 15 degrees celsius, the heat released is 2 x 10 ^15 J. I need to calculate a value for the total mass of lava that erupted. Many thanks for any advice Quote Link to comment Share on other sites More sharing options...
ronthepon Posted April 26, 2007 Report Share Posted April 26, 2007 Use the definition of specific heat. It is the amount of heat involved in changing the temperature of unit mass of the substance by a unit amount. Quote Link to comment Share on other sites More sharing options...
