The specific heat capacity of the lava is 1600 J kg^-1 degres celsuis ^-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.
calculate a value for the total mass of lava that erupted. give your answer in scientific notation.
plzzz some one help meeee....
i posted this question before and i still don't get how u work out the mass
Use the equation
(Heat release) = Mass x (specific heat) x (change in temperature)
Rearrange it algebraically to solve for the mass.
is this right ...in that case ..or where am going wrong !!
1600 J kg -1 °C -1 x 2 x 10 15 J x 1035 °C = 3.312 x 10 21 kgs
