When 300 J of heat is added to 25 gm of sample of a material its temperature rises from 25∘C to 45∘C. the thermal capacity of the sample and specific heat of the material are respectively given by
A calorimeter contains 5 kg of water at 30°C. A metal of mass 4 kg at 100oC is added to the calorimeter. The final temperature is recorded as 70oC. Find the specific heat capacity of the metal. Given: Specific heat capacity of water 4200 J kg–1 °C–1.
50g of copper is heated to increase its temperature by 10∘C. If the same quantity of heat is given to 10g of water, the rise in its temperature is (specific heat of copper = 420J/kg/∘C, specific heat of water = 4200J/kg/∘C)
The heat released by a copper ball of mass 1 kg when cooled from 100°C to 90°C is 8.4 kJ. Calculate the specific heat capacity of copper.
