2. Explain the difference between heat capacity and specific heat capacity. These are very similar in nature. The difference is that that heat capacity applies to a substance in general. Specific heat capacity is how much energy is required to raise 1 gram of a pure substance by 1˚C. Here is an example: Water has a certain heat capacity.

2.1 J/g˚C Heat capacity (c) of solid water 4.18 J/g˚C Heat capacity (c) of liquid water 334 J/g Heat of fusion H f 2260 J/g Heat of vaporization H v Energy Constants of Some Other Common Substances: Substance (state @ room temp) o Melting Point ( C) o Boiling Point (oC) Specific Heat Capacity for state (J/g C) Heat of Fusion Temperature Change and Specific Heat The amount of energy that raises the temperature of 1 kg of a substance by 1 K is called the specific heat of that substance. The symbol for specific heat is c. If W = 0, so no work is done by or on the system, then the heat needed to bring about a temperature change ∆T is
Specific properties are intensive. Thus, specific volume is volume per mass, specific internal energy is internal energy per mass, and specific enthalpy is enthalpy per mass. Specific properties will be identified by a “^” symbol above them; thus, Vˆ = specific volume (units: volume/mass; e.g. m 3/kg, ft 3/lb

A slice of pizza contains 180 nutritional Calories. Convert this energy into joules. 2. The advantage of doing so is that you need not learn a "formula" for solving specific heat problems. Problem Example 2. How many joules of heat must flow into 150 mL of water at 0° C to raise its temperature to 25° C? Solution: The mass of the water is (150 mL) × (1.00 g mL –1) = 150 g. The specific heat of water is 4.18 J K –1 g –1.
You will find that the specific heat is sometimes given the symbol "s" and sometimes the symbol "c". The specific heat of a substance is the amount of heat needed to increase the temperature of 1 gram of it by 1 K (which is the same as 1°C). So for water (the value you are most likely to come across), the specific heat is 4.18 J g-1 K-1.

After doing the necessary calculations, we found the average heat capacity of our calorimeter to be 102.56 J/degrees C. This number is a high number compared to the numbers that many of my classmates got (most were in the 80s). The higher the number, the better the calorimeter, so our high number could mean that our calorimeter was working
