C.lower density when frozen
WebWhen we freeze a liquid, we lower its temperature and it becomes a solid. The solid states of other liquids are denser because the molecules pack together tightly when the kinetic energy (temperature) decreases. The hydrogen bonds in water ice are indeed strong, but their orientation causes molecules to push apart, actually lowering density. WebApr 14, 2024 · where C p,frozen = apparent specific heat of frozen food (kJ/kgK) X s = mass fraction of solids (decimal) X w0 = mass fraction of water in the unfrozen food …

WebThe density decreases from 0.9970 g/mL to 0.9718 as it is heated. This makes sense because, as heat is added to the liquid water, there is greater kinetic energy of the molecules and there are also more vibrations of the water molecules. Together these mean that each H 2 O unit in liquid water takes up more space as the temperature increases. http://butane.chem.uiuc.edu/pshapley/GenChem1/L21/2.html
