What is specific specific heat?
Specific heat, the quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree. The units of specific heat are usually calories or joules per gram per Celsius degree. For example, the specific heat of water is 1 calorie (or 4,186 joules) per gram per Celsius degree.
Is europium a good heat conductor?
Europium is a metal element so it is a good thermal conductor and a good electrical conductor. Europium is a shiny solid at standard temperature and pressure and has a high melting point.
What is specific heat answer?
The energy required to heat something is proportional to the mass and temperature change of the material. Specific heat is the amount of heat per unit mass needed to increase the temperature of a material by one degree Celsius or Kelvin.
What is L in specific heat?
The specific latent heat (L) of a material… is a measure of the heat energy (Q) per mass (m) released or absorbed during a phase change.
What is an example of high specific heat?
Water has the highest specific heat of any liquid. It requires 4.184 Joules to raise the temperature of one gram of water by one degree Celsius. This is the most energy required to raise a liquid by one degree. Water’s high specific heat is very useful to life.
How do you find specific heat?
Calculate specific heat as c = Q / (mΔT) . In our example, it will be equal to c = -63,000 J / (5 kg * -3 K) = 4,200 J/(kg·K) . This is the typical heat capacity of water.
What does europium look like?
Europium is a soft, ductile, silvery-white metal that instantly oxidizes in air. It is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150 oC to 180 oC.
Where is europium used?
nuclear reactors
Europium is excellent at absorbing neutrons, making it valuable in control rods for nuclear reactors. Europium-doped plastic has been used as a laser material. It is also used in making thin super-conducting alloys.
What is CP and CV?
CV and CP are two terms used in thermodynamics. CV is the specific heat at constant volume, and CP is the specific heat at constant pressure. Specific heat is the heat energy required to raise the temperature of a substance (per unit mass) by one degree Celsius.
How do I calculate specific heat?
What is an example of low specific heat?
Metals such as iron have low specific heat. It doesn’t take much energy to raise their temperature. That’s why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat.
Why is specific heat of water so high?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy. Water has the highest specific heat capacity of any liquid.
What kind of temperature does europium ignite at?
Europium is a soft, ductile, silvery-white metal that instantly oxidizes in air. It is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150 oC to 180 oC.
What are the properties of europium in water?
Characteristics: In water it reacts in a similar way to calcium, producing europium hydroxide and hydrogen gas. Unlike most other rare earth metals, europium can form stable compounds in the divalent state, Eu 2+ (europous) as well as the usual trivalent state, Eu 3+ (europic).
What is the color of the element europium?
Complete and detailed technical data about the element Europium in the Periodic Table. H Home Background Color: He Li Be Europium Main Page Black White Gray B C N O F Ne Na Mg
Why is europium considered to be a toxic metal?
Europium is considered to be mildly toxic. The metal dust is considered to be a fire and explosion hazard. Europium is a soft, ductile, silvery-white metal that instantly oxidizes in air. It is the most reactive of the rare earth metals and ignites in air at temperatures in excess of 150 o C to 180 o C.
