A calorimeter is a device designed to show us how many calories are in an object. But before I can explain what a calorimeter is and how it works, we have to go back and explain what specific heat and calories are. A calorie is a measure of energy in an object. On Big C Calorie is equal one thousand little c calories. Then specific heat is the amount of energy required to raise one gram of water one degrees Celsius. Therefore when we use a calorimeter we are trying to find the cp of of the object not anything else. When we want to find out the cp of an object we put a heated material into the calorimeter that is filled with room temperature water. When one minute has passed we take out whatever object was in the calorimeter and record the change in temperature of the water. Then we put the data through the formula and see what the final result is.
A calorimeter is an insulated device in which we can calculate heat lost and heat gained. We can find the Cp, or specific heat, of water by starting at room-temperature water (avg: 21-23°C) and then pouring in boiling water (100°C) and finding the difference using an equation. The final result can either be avg change in temperature in boiling or room-temperature water, or the avg. final temperature.
A calorimeter measures the amount of energy of an object. It usually measures the specific heat of an object. Since the specific heat of water is 1 calorie per gram * degrees Celsius, it is used as a basis for measuring specific heat. That is why when measuring the amount of energy in an object, we put water inside the container at room temperature. After the room temerature water is put inside the container, an object is put into the calorimeter as well, usually at boiling temperature (though much heat is lost to environment, so it is usually never exactly 100 degrees Celsius). After the specified amount of time, you record the temperature of the water inside the calorimeter, record the change in temperature, and use a formula to figure the Cp of the water and/or object.
Because a calorimeter is designed to prevent the transfer of energy to and from the outside environment, we can be sure that energy transfers are only occurring between the samples that are being tested. This means we can be confident in the temperature changes we measure, and we can use them in the formulas that will reveal the amount of energy in an object.
