The specific heat of water is 4.18 j/(gi°c) and that of wood is 1.97 j/(gi°c). which statement is correct? regardless of mass, wood will heat up less than water if the same heat is added. given equal masses, wood will heat up less than water if the same heat is added. given equal masses, water will heat up less than wood if the same heat is added. regardless of mass, water will heat up less than wood if the same heat is added.

Specific heat is the amount of heat required to raise the temperature of 1 g of a sample by 1 C

The heat Q absorbed to increase the temperature by ΔT of a substance of mass m and specific heat c is given as:

Q = mcΔT

It is given that the specific heat of water = 4.18 J/gC and that of wood = 1.97 J/gC. Since c(water) > c(wood), for the same mass m, more heat is required to heat water that wood,

Therefore, Given equal masses water will heat up less than wood if the same heat is added.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
