The temperature of a bomb calorimeter was found to rise by `1.617K` when a current of `3.20A` was passed for `27s` from a `12V` source. Calculate the calorimeter constant.

Text Solution

Verified by Experts

Enegry absorbed by the calorimeter
`1 xx t xx V = 3.2 xx 27 xx12 = 1036.8 J`
Calorimeter constant `(ms)` can be calculated as,
`q = ms Deltat`
`1036.8 ms xx 1.617`
`ms = 641.187 kJ`

In a constant volume calorimeter, 3.5 g of a gas with molecular weight 28 was burnt in excess oxygen at 298.0 K . The temperature of the calorimeter was found to increase from 298.0 K to 298.45 K due to the combustion process. Given that the heat capacity of the calorimeter is 2.5 kJ K^(-1) , find the numerical value for the enthalpy of combustion of the gas in kJ mol^(-1)

When 1.0 gm of fructose C_(6) H_(12) O_(6) (s) is burnt in oxygen in a bomb calorimeter, the temperature of the calorimeter water increases by 1.56^(@)C . If the heat capacity of the calorimeter and its contents is 10.0 kJ//^(@)C . Calculate the enthalpy of combustion of fructose at 298 K.
