Raising the temperature of 10.0 g of water from 10.0°C to 20.0°C requires 418 J, while that increasing 10.0 g of aluminum from 10.0°C to 20.0°C requires 89.7 J. The reason why water requires more heat is because___________.A. water is a liquid and aluminum is a solid. B. 10.0 g of water occupies a larger volume than 10.0 g of aluminum. C. Water has a higher specific heat than aluminum. D. water has higher potential energy than aluminum.

Respuesta :

Answer

C. Water has a higher specific heat than aluminum.

Explanation

Increasing of kinetic energy means the intermolecular attraction decreases. For water between any two molecule, there are strong H-bond (hydrogen bond). So, to overcome their bond energy we need more amount of heat than another substance. So water has a high specific heat capacity.
