Question

some amount of hot water at 90 degree celsius is mixed with some amount of cold water of 20 degree Celsius if total water weight is 50 kg at 45 degrees celsius calculate the amount of hot and cold water​

Answer 1

Answer:

• 4,200 joules
• 4,200 joulesThe specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
