PVC is one of the four plastics whose combined usage accounts for 75% of the worldwide usage of plastics (PE, PP, PVC, and PS). Porcelain and stoneware materialsare about as resistant to acids and chemicals as glass, but with greater strength. Therefore, the final temperature will be greater than 25 . A fracture surface of this alloy has a white appearance, and thus it is termed white cast iron. 4 Does water have a higher specific heat than alcohol? At ambient pressure and temperature the isobaric specific heat, CP, of liquid ethanol is 2.57 [kJ/kg K] or 0.614 [Btu/lb F] = [cal/g K], while the isochoric specific heat, CV, is 2.18 [kJ/kg K] or 0.520 [Btu/lb F] = [cal/g K]. The ratio of the specific heats of the mixture is C /C = 1.4. This value for Cp is actually quite large. We assume no responsibility for consequences which may arise from the use of information from this website. Thespecific heatfor some commonly usedliquids and fluidsis given in the table below. Limestone is a type of carbonate sedimentary rock. Polypropylene is recyclable. As water requires more time to boil than does alcohol, you might conclude .
