What is meant by specific heat capacity of iron is 470 J/ kg °C ?
Amount of heat to increase 15°C temp, 5 kg silver. If same supplied to silver, calculate change in temp. specific heat capacity of silver = 234 J/ kg°C and wsteel = 447 J/kg°C
What will be the temp raised for 50 kg water with 30°C , power 1000 W giving 3.6 * 10 ^ 6 J.
Calculate heat energy when, 1 kg m of water at 70°C reduced to 40°C.
What will be the temp ? if milk 200 ml, 90°C mixed with 15° C 10 ml water.
IF 100 W heater takes 2 min to increase temp to 25 to 30 °C. What is specific heat capacity ?
What will be the final temp of 20 kg of water at 30°C if 1000 W heater gives 4.2 * 10^3 KJ?
What is the change in temp of water, if heat = 5*1065, 20 litres water.
How much energy is released, 5 kg mass of iron, 17 degree to 2 degree temp.
What will be the quantity of heat energy lost. if m = 200 gm mercury, cooled from 10 to -10 °C
