The amount of enthalpy required to heat 50.0 g of liquid ethanol from 23.0°C to ethanol vapor at 78.3°C is 2) 49.5 kJ.

What is J GC?

Specific Heat Capacity (C or S ) – The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity of the substance. The quantity of heat is frequently measured in units of Joules(J). The specific heat of water is 4.18 J/g° C.

How many joules are required to raise the temperature?

The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4,200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.

What is the amount of heat in joules required to increase the temperature?

Quantifying Specific Heat Quantitative experiments show that 4.18 Joules of heat energy are required to raise the temperature of 1g of water by 1°C. Thus, a liter (1000g) of water that increased from 24 to 25°C has absorbed 4.18 J/g°C x 1000g x 1°C or 4180 Joules of energy.

What amount of heat in kJ is required to vaporize 115g of ethanol?

115.00 g x 0.940 kJ/g = 108 J (3 sig.

What kind of heat is needed for ethanol?

Ethanol – Specific Heat, C p and C v Specific heat (C) is the amount of heat required to change the temperature of a mass unit of a substance by one degree. Isobaric specific heat (Cp) is used for ethanol in a constant pressure (ΔP = 0) system.

Why is the specific heat of ethanol lower than copper?

Copper’s is lower because metals in general are more energy conductive than organic solvents. The specific heat of ethanol is 2.46 jg degrees calcius what is the heat energy required to raise the temperature of 193g of ethanol from 19 degrees Celsius to 35 degrees Celsius?

What is the isochoric specific heat of ethanol?

Isochoric specific heat (C v) is used for ethanol in a constant-volume, (= isovolumetric or isometric) closed system. At ambient pressure and temperature the isobaric specific heat, C P, of liquid ethanol is 2.57 [kJ/kg K] or 0.614 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, C V, is 2.18 [kJ/kg K] or 0.520 [Btu/lb °F] = [cal/g K].
