What is an example of high specific heat?
An example of a high specific heat is water’s specific heat, which requires 4.184 joules of heat to increase the temperature of 1 gram of water 1 degree Celsius. Scientifically, water’s specific heat is written as: 1 calorie/gm °C = 4.186 J/gm °C.
Does ammonia have a higher specific heat than water?
NH3 (molecular weight 17) has even a slightly higher *specific* heat capacity than water at similar conditions, again mainly because of the low molar mass. So there is nothing really peculiar about the specific heat capacity of water.
Why is water specific heat?
Water has a higher specific heat capacity because of the strength of the hydrogen bonds. It requires a significant of energy to separate these bonds.
What is the specific heat of ammonia?
At ambient pressure and temperature the isobaric specific heat, CP, of ammonia is 2.2 [kJ/kg K] or 0.52 [Btu/lb °F] = [cal/g K], while the isochoric specific heat, CV, is 1.6 [kJ/kg K] or 0.39 [Btu/lb °F] = [cal/g K].
What is the specific heat of HCl?
4.04 J/g

What state of matter is carbon dioxide at 20 degrees Celsius?
Carbon dioxide is a gas at room temperature. The sublimation point of carbon dioxide (dry ice) is −78.5∘C .
Does carbon dioxide have a high heat capacity?
At high temperatures above 1500 K (3223 oF) dissociation becomes appreciable and pressure is a significant variable….Specific heat of Carbon Dioxide gas – CO2 – temperatures ranging 175 – 6000 K.
| Carbon Dioxide Gas – CO2 | |
|---|---|
| Temperature – T – (K) | Specific Heat – cp – (kJ/(kg K)) |
| 275 | 0.819 |
| 300 | 0.846 |
| 325 | 0.871 |
How do you calculate CP of CO2?
Elliott and Lira (Introductory Chemical Engineering Thermodynamics) give the Enthalpy of formation of CO2 as being -393.51KJ/mol and they give the ideal heat capacity equation as being CP(J/mol*K)= A+B(T)+C(T^2)+D(T^3), and for CO2 the constants are given by them as A=1.980E+1, B=7.344E-2, C=-5.602E-5, D=1.715E-8.
What is CP for ideal gas?
The ratio of the specific heats γ = CP/CV is a factor in adiabatic engine processes and in determining the speed of sound in a gas. This ratio γ = 1.66 for an ideal monoatomic gas and γ = 1.4 for air, which is predominantly a diatomic gas.
What is the value of CV for monoatomic gas?
Therefore, the correct answer is Cv values for monoatomic and diatomic gases are 32R and 52R respectively. Note: Note that for solids and most liquids the value of specific heat capacity at constant pressure Cp∼Cv and this fact also helps to solve the questions relating to specific heat capacity and do not confuse.
