Question

A student claims that water's polarity is the reason it has a high specific heat. What method could the student use to test his claim? (2 points)

a
Perform research to see if other polar molecules have high specific heat

b
Measure how much energy it takes to increase the temperature of water by one degree

c
Mix water with an acid and test the new specific heat

d
Determine how dissolving salt in water affects the specific heat

Answer 1

Step-by-step explanation:

a. Yes, other polar molecules also have high specific heat

b. To heat 1g of water up by 1 degree C, it takes 4.186J of energy

c. The specific heat of an acid is less than water; e.g. HCl is 4.04J/g-C

d. Dissolving salt in water also lowers water's specific heat, e.g. NaCl is 0.86J/g-C
