What is the specific heat of titanium?
0.72 J/g°K
The specific heat of titanium has been measured over a temperature range from 600° to 1345°K. The specific heat at 600°K is 0.72 J/g°K ±2.5%, and increases to 0.93 J/g°K ±6% just below the transition, which takes place at 1155°K.
What is J in heat capacity?
The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.

What is the specific heat of sodium chloride?
As the specific heat capacity of NaCl is 0.86J/gK, it would make sense that the specific heat capacity of an aqueous solution containing NaCl should decrease.
Why is hydrogen heat capacity so high?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
What is the heat capacity of HCl?
4.04 J/g
The specific heat of 1 M HCl solution is 4.04 J/g•°C. 4.
Does salt water have a higher specific heat than water?
Seawater of 35 psu has a specific heat of 0.932 compared with 1.000 for pure water.
What is the specific heat of iodine vaporization?
Overview Heat of Vaporization 20.9 kJ/mol Specific Heat 429 J/ (kg K) [note] Adiabatic Index N/A Neel Point N/A
How to describe the physical properties of iodine?
Iodine Appearance & Characteristics 1 Structure:layers of I2 Color:bluish-black Hardness:mohs. 2 In small doses, iodine is slightly toxic and it is highly poisonous in large amounts. 3 Iodine is a bluish-black, lustrous solid. 4 Although iodine is a non-metal, it displays some metallic properties.
What happens to iodine vapor in a confined space?
Emits toxic vapor at room conditions; vapor becomes visibly purple when its concentration builds up in a confined space. Nearly insoluble in water but very soluble in aqueous solutions of iodides. OtherSolid; PelletsLargeCrystals; WetSolid
How many milligrams of iodine do you need daily?
The radioactive isotope iodine-131 is sometimes used to treat cancerous thyroid glands. Iodine is an essential element for humans, who need a daily intake of about 0.1 milligrams of iodide. Our bodies contain up to 20 milligrams, mainly in the thyroid gland.
