A developmental psychologist is examining the development of language skills from age 2 to age 4. Three different groups of children are obtained, one for each age, with n = 18 children in each group. Each child is given a language-skills assessment test. The resulting data were analyzed with an ANOVA to test for mean differences between age groups. The results of the ANOVA are presented in the following table. Fill in all of missing values:

Source:   SS     df     MS    F

Between:  48                        -

Within:

– – –

Total    252               -         -

Fifty milliliters of 100% H 2 SO 4 at 25 ° C and 84.2mL of liquid water at 15 ° C are mixed. The heat capacity of the product solution is 2.43J/(g  ° C).

(a) Estimate the maximum temperature attainable by the product solution and state the conditions under which this temperature would be attained, using heat of mixing data from Table B.11.

(b) Give several reasons why the temperature calculated in Part (a) could not be attained in practice.

(c) Estimate how much heat would have to be transferred from the mixing vessel to keep the temperature of the product solution at 25 ° C. (You should be able to solve this problem quickly by looking back at the enthalpy table of Part (a).)
