So if we talk about the side of cubic bronze, so it is basically equals to 1 .5 centimeter or if we convert it into meter, so it will be 0 .015 meters.
00:18
Now we need to calculate the volume of cubic bronze so it will be equal to side cube so it will be equal to 0 .015 and its whole cube so it will be equal to the value 3 .375 into 10 raised to the power minus 6 meter cube.
00:38
Now from here we know that the density of bronze is equal to the value 8890 kg per meter cube.
00:52
So from here we can simply calculate the mass.
00:55
So mass will be equal to density multiplied by volume which is equal to in this case 8890 multiplied by the volume which is 3 .375 into 10 raised to the power minus 6 meter cube.
01:14
So it will be equal to the value 30 grams.
01:18
That is it is equal to the value 3 into 10 raised to the power minus 2 kg and we have converted it into 30 grams.
01:24
So we can also write it as that equal to 3 into 10 raised to the power minus 2 kg that we converted to grams that is 30 grams.
01:35
Now from here we can simply use the formula which is delta h is equal to ms delta t or h that is enthalpy change is equal to mass into specific heat capacity multiplied by the delta t which is change in temperature...
