what mass of water could be warmed from 23.8 C to 46.3 C by a 100 g metal pellet at
116 C
Homework Equations
The Attempt at a Solution
well i know the formula qsurr=ms[tex]\Delta[/tex]T
so qwater=ms[tex]\Delta[/tex]T
but then how do i work my way around when the heat capacity isn't also given
i'll really appreciate all the help i can get.
Constant pressure calorimetry is a technique used in thermodynamics to measure the change in enthalpy of a chemical reaction or physical process at a constant pressure. This is done by measuring the heat exchange between a reaction or process and its surroundings.
In this type of calorimetry, the reaction or process is carried out in a vessel called a bomb calorimeter, which is surrounded by a water jacket. The temperature of the water is then measured before and after the reaction or process, and the change in temperature is used to calculate the heat released or absorbed.
Constant pressure calorimetry is advantageous because it allows for the measurement of enthalpy changes at conditions similar to those found in industrial processes and biological systems. It also provides more accurate results compared to other calorimetry techniques, such as constant volume calorimetry.
Constant pressure calorimetry is commonly used in the study of chemical reactions, such as combustion reactions, and in the determination of the heat of formation of compounds. It is also used in the food industry to measure the caloric content of foods and in environmental science to study the heat exchange in ecosystems.
One limitation of constant pressure calorimetry is that it assumes that the system is at a constant pressure, which may not always be the case. It also does not take into account any heat exchange with the surroundings that occurs during the reaction or process. Additionally, it may be difficult to accurately measure small heat changes using this technique.
