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 a
= mc AT to calculate the mass of water needed to cool the lava.
