What is the specific heat of solid ethanol?
The specific heats of solid and liquid ethanol are 0.97 J/gK and 2.3 J/gK, respectively.
What is the definition of standard heat of formation of ethanol?
The enthalpy change for this reaction corresponds to the standard enthalpy of formation of ethanol. By definition, the standard enthalpy of formation is the enthalpy change when one mole of substance forms from its elements in their standard states under standard conditions.
How do you calculate heat of combustion?
How do you find the heat of combustion?
- Divide the number of moles of water vaporized by number of moles of fuel combusted.
- Find the product of heat of vaporization of water and the ratio of moles.
- Add the resultant to lower heating value of the fuel to obtain heat of combustion.
How do you calculate heat capacity experimentally?
Steps to determine the specific heat capacity.
- Place a beaker on a balance and press zero.
- Now add the oil to the beaker and record the mass of the oil.
- Read the starting temperature of the oil.
- Connect a joulemeter to the immersion heater.
- Time for thirty minutes.
What is the unit of heat capacity?
Joule per kelvinHeat capacity / SI unit
Heat capacity is defined as the amount of heat energy required to raise the temperature of a given quantity of matter by one degree Celsius. Heat capacity for a given matter depends on its size or quantity and hence it is an extensive property. The unit of heat capacity is joule per Kelvin or joule per degree Celsius.
What is the molar heat capacity of ethyl alcohol?
