Students have asked these similar questions
If the dissolution of a salt in water is an endothermic reaction, how will the temperature of the solution
change as the reaction proceeds?
O The solution will heat up.
O There is insufficient information to answer the question.
O The solution will cool down.
There will be no change in temperature.
Explain the concept of specific heat and how the specific heat of water enables the human body to remain at a relatively constant temperature. Use details to support your answer.
