Lava often flows into the ocean from volcanoes. A student wants to know how much water would be needed to cool a small sample of lava to 100°C. She calculates that the water would need to absorb 2,000 kJ of energy to
cool the lava. She also finds the information in the table.
Temperature of ocean water 26.0°C
Specific heat of water 4.186 kJ/kg°C
Use the equation q= mc^T to calculate the mass of water needed to cool the lava.
A
3.79 kg
B
4.78 kg
С
6.46 kg
D
18.4 kg

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
