A copper calorimeter of mass 120 g ( $s = 390$ J $k g^{- 1}$ $K^{- 1}$ ) is used for a heat measurement. Find its water equivalent in grams (two decimals; $s_{w a t er} = 4200$ ).

Answer:

11.14

Solution:

The water equivalent is $w = \frac{m s}{s _{w}} = \frac{0.12 \times 390}{4200} = 0.0111$ kg = $11.14$ g.
