How much heat is released when iron ball, 4 kg cools from 20°C to 10°C.
if 600 J is added to 20 gm water, what is rise in temperature ?
If 44000 J of heat is required for 1 kg of paraffin to increase the temperature by 20°C. amount of heat required for 2 kg,by 10 °C
Calculate the final temp when 2100 J of heat is given to mercury of mass 1 kg at 15°C. mercury specific heat capacity is 140 J/ kg °C.
When same quantity of heat is supplied to 300 gm of water, 150 gm of oil. rise in water 10 C, OIL 40 C. Calculate Q and S.
How much heat is required to increase temp of frying pan by 80°C if the mass of the pan is 0.5 kg and its specific heat is 480 J/kg°C
What is the final temperature, 80 kJ energy given to pressure cooker, mass 4 kg,30°C, specific heat is 1000 J/ kg°C.
Calculate the final temp of mixture, 10 kg hot water 90 °C with 20 kg water at 10°C.
Calculate the specific heat capacity. 200 gm mass, metal at 83°C in 300gm water at 30°C
Calculate the amount of heat, normal water temp 5°C , 20 kg water to be heated at 35°C.
