100 mL of water at 25oC and 100 mL of alcohol at 25oC are both heated at the same rate under identical conditions. After 3 minutes the temperature of alcohol is 50oC. Two minutes later the temperature of water is 50oC. Which liquid received more heat as it warmed to 50oC

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.

i think that the answer is c
