HEAT CAPACITY Thesis statement: The heat capacity can be referred to the variable quantity that is measurable and is equal to the amount of heat change in an object. The quantity of heat is equal to the change in temperature times the specific heat capacity times the mass of the object involved. Question An ice cube having a mass of 50 grams and an initial temperature of -10 degrees Celsius is placed in 400 grams of 40 degrees Celsius water. What is the final temperature of the mixture if the effects of the container can be neglected? Discuss your answer. Answer FINAL temperature = 25.6°C Explanation. Q = M × c × ΔT Q= the amount of heat energy that has been transferred. M= the mass of the object C= the heat capacity of the object T= Change in temperature of the object. The units of all the variables should be in standard form. Temperature change = Kelvin (K) Mass = grams (g) Heat capacity = J/g °C. The amount of heat lost by the water is gained by the ice. Let’s assume the final temperature is T. Mass of water ×heat capacity of water × change in temperature= ((mass of ice × latent heat of fusion of ice) + (mass of ice × heat capacity of water × temperature change) ...
