Ashton Anderson 29 Calorimetry S - Page 1 preview imageCalorimetryWhat is the relationship between heat energy and temperature?Why?____________________________________________________When a substance is heated, the temperature of that substance increases. Will the same amount of energycause different substances to have identical temperature increases? Will the same amount of energy beneeded to cause identical temperature increases in different amounts of the same substance? In this activityyou will explore how mass, temperature, heat energy, and the type of substance are related.After heating for 5 minutes ata rate of 30 Joules per minute1. In Model I, which container holds more grams ot water?8 qt Stockpot2. Consider the process described in Mode] 1:a.How many joules of energy' were added to the saucepan?150b.How many joules of energy were added to the stockpot?150c.In which container did the liquid gain more energy or did both gain rhe same amount?Explain your reasoning.They both gained the same amount, it is just dispersed differently.d.For each container include whether the temperature is expected to increase, decrease orremain the same after heating. Explain your reasoning.It isbeing heated so it would increase in heat.Calorimetry]

In the data tables in Model 2, what does AT mean?Change in Temperature4. Which experiment in Model 2 illustrates how the amount of energy needed to achieve the sametemperature change depends on the mass of water?Expiriment 15. Which experiment in Model 2 illustrates how different amounts of energy result in differenttemperature changes when the mass of water is constant?Expinmenl 2> 6. Why was it necessary to perform three experiments to find the relationships betwren mass,temperature change, and energy?Because we can see the differences and effects all of the variables have on the expirlmenl.
