25.Derive the value of R in terms of calorie

Q. What is the value of 1 calorie in joules?

Q. 12.2gm solid benzoic acid is combusted in bomb calorie meter t ${25}^0$C? Rose from ${25}^0$C to ${75}^0$C if heat capacity of calorie meter is ${50JC}^0$? Calculate the change in internal energy? Calculate the molar enthalpy of combustion at ${25}^{0}C$.

Q.

A calorie is a unit of heat or energy and it equals about 4.2 J where 1J = 1 kg m²s^–2. Suppose we employ a system of units in which the unit of mass equals α kg, the unit of length equals β m, the unit of time is γ s. Show that a calorie has a magnitude 4.2 α^–1 β^–2 γ² in terms of the new units.

Q. A calorie is a unit of heat or energy and it equals about $4.2J$ where $1J=1kg{m}^2{s}^{-2}$. Suppose we employ a system of units in which the unit of mass equals $\alpha kg$, the unit of length equals $\beta$ $m$, the unit of time is $\gamma s$. Show that a calorie has a magnitude $4.2$ ${\alpha }^{-1}{\beta }^{-2}{\gamma }^2$ in terms of the new units.
