Comparing heat energy from burning alcohols. In this investigation, students use a spirit burner to burn various alcohols while measuring and comparing the amount of heat energy produced. This experiment is suitable for pre-16 students, possibly as an introduction to a topic on fuels.
Study with Quizlet and memorize flashcards containing terms like What is the equation for converting a Fahrenheit temperature to a Celsius temperature?, What is meant by the term specific heat?, Why is a measured amount of water needed to determine the specific heat of a metal object? and more.
Calculate amount of calories absorbed by the water: Use q = m c T to calculate how much heat in calories was absorbed by the water. Specific heat (c) of water= 1 calorie / g °C,
26 sie 2024 · Calculate the mass change for each alcohol in the spirit burner. Use the calorimetry equation to find the heat of combustion of the alcohols in kJ per gram or kJ per mole: Enthalpy change equation: Q = m x c x ΔT. where: Q – energy transferred to water. m – mass of water heated.
The temperature of the water increased from 22°C to 71°C. Calculate the energy released per gram of fuel using the following equation. Energy given out = mass of water × 4.2 × temperature...
Q = m water •C water •ΔT water where C water is 4.18 J/g/°C. So if the mass of water and the temperature change of the water in the coffee cup calorimeter can be measured, the quantity of energy gained or lost by the water can be calculated.
