Specific heat (given) (Cal/g)

Change in temperature (℃ )
(End-short)

What is the dance that we learned in class today about our new equation?

Name all the Specific heat type and what they vary? ( if that makes sense)

Specific heat • Unique to every substance • Amount of energy required to increase 1g of substance by 1℃

High specific heat • Needs large amount of energy to change temp ex. Water
Low specific heat • Changes temp. easily ex.metal

Summary:

In today's class we talked a about the equation(s) of calorimetry. Calorimetry is the measurement of energy , and Calorimeter Is a tool used to measure energy by measuring the change in temperature. We also learn about the Specific heat, high specific heat, and low specific heat. But the main thing is that the new equation we learn today is

    Calorimetry is the measurement of the quantity of heat exchanged during chemical reactions or physical changes. For example, if the energy from an exothermic chemical reaction is absorbed in a container of water, the change in temperature of the water provides a measure of the amount of heat added.…

    Class average for a 80 and 120 drop count was recorded to be 0.041+/- 0.005 mL/drop. If a graduated cylinder is not available there is another way of adding more of the solution. The disposable pipet can transfer 0.5mL of the solution to the chemical reaction. When comparing a 10mL graduated cylinder, a 100mL beaker, and a 50mL graduated cylinder, the most precision peace of glass wear would be the 10 mL graduated cylinder with the true volume of water (calculated), class average, and uncertainties being 9.7896 +/- 0.05mL. The 50mL graduated cylinder comes in second place with a true volume of water(calculated), class average, and uncertainties being 50.0001 +/- 0.22mL. The third peace of glassware coming in as the least accurate would be the 100 mL beaker with a true volume of water(calculated), class average, and uncertainties being 59.9999 +/- 0.82mL.…

    In this lab, we dissolved a calcium-enriched tablet and participate the calcium ion as calcium carbonate. Our purpose is to determine the masses of calcium carbonate and calcium ion, to determine the mass percent of calcium ion in the tablet and to compare the masses and the percent with the listed tablet ingredients. This time we used a 150mL beaker, analytical balance, forceps, a 50mL graduated cylinder, a glass rod, beaker tongs, a hot plate, two 16 x 125-mm test tubes, centrifuge, a medicine dropper, a filter paper, a filter funnel, a 250-mL Erlenmeyer flask, a watch glass, a drying oven, a spatula and a red litmus paper. The chemicals we need were 20mL of 2.0M HCl, a calcium-enriched tablet and 25mL of 1.0M Na2CO3 solution.…

    The specific heat capacity of a substance is the amount of thermal energy required to heat one gram of that substance by one degree. It is an intensive property, as opposed to the heat capacity, which is an extensive property that depends on the amount of substance present. In this experiment, the heat capacity is determined by measuring the change in temperature of the cold water when a hot metal (that does not react with the water) is placed in it. It is assumed that the specific heat capacity is constant in the temperature range, although in reality it does vary with temperature.…

    A calorimeter is an instrument used to measure the change in heat in a reaction. Inside a calorimeter it is filled with water. To find the specific heat of a substance you place the substance inside the water, then measure the change in the temperature of the water and the change in temperature of the substance. The final temperature and amount of heat transferred will always be equal (q of water= q of substance). Then, using basic algebra, you can figure out the specific heat of the…

    This is known as specific heat capacity; it measures the amount of energy needed to raise the temperature of that particular substance by 1 degree Celsius. Specific heat capacity was first discovered in the 18th century by a Scottish scientist by the name of Joseph Black who noticed that different substances of equal masses required distinctive amounts of heat to raise them to similar temperature intervals (Encyclopædia Britannica 2014). The specific heat capacity of water is 4.184 J/g°C. Energy is most commonly measured joules (J) or kilojoules (kJ) during the study of heat transfer between two substances (Tuckerman n.d.); however, there is another measurement for energy which is used to measure the amount of energy in food, and this is referred to as food calories. Food calories are equal to 1000 heat calories and 1 heat calorie is equal to 4.184 joules (Calories in Food – A Factor in Weight Maintenance and Weight Loss n.d.). Consequently, it can be seen that the specific heat of a substance can also be measured in calories. Therefore, the specific heat capacity of water can also be written as 1 cal/g°C. In this lab, the calculations were done using food calories and heat calories in order to determine the caloric content of one marshmallow per…

    3.4007g of potassium phosphate was weighed and placed in 300 mL beaker. Then, 125 mL of water was added into the beaker that contained potassium phosphate. The mixture was dissolved using the stirring rod, and then the magnetic stirring bar was placed in the beaker for further dissolve when measuring the pH. The pH meter was used to measure the solution, and the data was documented at pH 4.6. This was the starting point. Next, 1M NaOH was slowly added into the buffer to make it to pH 6. Then, the buffer was transferred to a 1000 mL graduated cylinder, and 125mL of distill water was added to the buffer.…

    Given appropriate chemicals and equipment, the specific heat capacity and molar mass of a metal, enthalpy of neutralization of an acid and base, and the enthalpy of solution of an unknown salt can be determined by following specific procedures. All of these procedures require the use of a calorimeter, which are of two types: a bomb calorimeter and a coffee cup calorimeter. Calorimeters are simply devices used to measure the amount of heat gained or lost in a system. Although this is not completely true, they are treated as isolated systems. A simple coffee-cup calorimeter can be constructed using two Styrofoam cups nested inside each other. The Styrofoam prevents heat loss to the surroundings, which makes it an ideal calorimeter.…
