A 10.0 g piece of metal is placed in an insulated calorimeter containing 250.0 g of water initially at 20.0 °C. If the final temperature of the mixture is 25.0 °C, the heat change of water will be 5230 J.
Weight of metal = 10.0 g
Weight of water = 250.0 g
Initial temperature of water (Ti) = 20.0 °C
Final temperature of water (T2) = 25.0 °C
The specific heat capacity of water is 4.184 J/g.°C
We can calculate the heat change of water by the following equation;
<em>Q = mwater × Cwater × (T2-Ti)</em>
Q = 250.0 g × 4.184 J/g.°C × (25.0 - 20.0) °C
Q = 5230 J

Answer:
Oiling is done on a regular basis to sewing Machine because in the machine there are lots of machinery parts i.e. wheels and axels, etc. which are in continuous use and they possess so much frictional force between them that wear tear may be observed in those parts.
