Chemistry problem?

Question

1. Two grams of salt A were added to 50 mL of water. The initial and final temperatures were recorded (see table). In a separate experiment, 2 grams of salt B were added to 50 mL of water and its initial and final temperatures were recorded. 

2 grams of salt A dissolved in 50 mL water	2 grams of salt B dissolved in 50 mL water
Initial temperature, °C	20 °C	Initial temperature, °C	20 °C
Final temperature, °C	35 °C	Final temperature, °C	10 °C

1. What can be said about the flow of energy in the two experiments?
2. For salt A, the energy flows from the water to the salt. For salt B, the energy flows from the water to the salt.
3. For salt A, the energy flows from the salt to the water. For salt B, the energy flows from the salt to the water.
4. For salt A, the energy flows from the salt to the water. For salt B, the energy flows from the water to the salt.
5. For salt A, the energy flows from the water to the salt. For salt B, the energy flows from the salt to the water.
6. There is no net flow of energy between the water and the salt in either experiment.

Answer 1

C. For salt A, the energy flows from the salt to the water. For salt B, the energy flows from the water to the salt.
