The specific heat capacity of water is ____ `cal//g^(@)C`

Answer

A, B

Explanation

`(Q/t)=(KA(T_1-T_2))/(Lms)`
`Rise in temperature in T_2=(KA(T_1-T_2))/(Lms)`
Fall in temperature om
`T_1=(KA(T_1-T_2))/(Lms)`
`Final temperture T_1=T_1-(KA(T_1-T_2))/(Lms)`
`Final temperature T_2=T_2+(KA(T_1-T_2))/(Lms)`
`implies(dT)/(dt)=(2KA(T_1-T_2))/(Lms)`
`impliesIn(T_1-T_2)/(2(T_1-T_2)=(2KA)/(Lms)t`
`In 2=(2KA)/(Lms)t`
`t=(Lms)/(2 KA)In 2`.
