What is the heat energy taken by 50 g of cold water at 20 degrees C in previous problem?
200 g of hot water at 80°C is added to 300 g of cold water at 10°C. Calculate the final temperature of the mixture of water. Consider the heat taken by the container to be negligible. The specific heat capacity of water is 4200 J kg-1 °C-1
One calorie is the heat energy required to raise the temperature of one gram of water by ___ degree Celsius at a pressure of one atmosphere.
