HOW MUCH HEAT ENERGY TRANSFERRED TO THE COLD WATER
To calculate the amount of heat energy transferred to cold water, you need to know the mass of the water and the change in temperature.
The formula to calculate the heat energy transferred is:
Q = mcΔT
Where:
Q is the heat energy transferred in joules (J)
m is the mass of the water in kilograms (kg)
c is the specific heat capacity of water (approximately 4,186 J/kg°C)
ΔT is the change in temperature in degrees Celsius (°C)
Step 1: Determine the mass of the water in kilograms.
If you know the volume of the water, you can convert it to mass using the density of water, which is approximately 1 kilogram per liter (or 1 gram per milliliter).
Step 2: Determine the change in temperature.
Subtract the initial temperature of the water from the final temperature. Ensure that the temperatures are in degrees Celsius.
Step 3: Calculate the heat energy transferred.
Multiply the mass of the water (in kilograms), the specific heat capacity of water, and the change in temperature.
By following these steps and plugging the values into the equation, you can determine the amount of heat energy transferred to the cold water.
