What is mercury gas?

Elemental (Metallic) Mercury At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. If heated, it is a colorless, odorless gas.

What is the meaning of specific heat capacity of mercury is 140 Joule per kg degree Celsius?

The specific heat capacity of mercury is 138 JKg-1 0C-1 means that 138 joule of heat energy is required to raise the temperature of 1 kilogram of mercury by 1 0C.

Which gas has highest specific heat capacity?

Hence only Hydrogen has highest specific heat capacity.

Which material has highest specific heat?

Liquid water
Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1.

What is the specific heat capacity of water in J kg C?

4182 J/kg°C
The exact value of the specific heat capacity of water is 4182 J/kg°C.

What is molar specific heat of gas?

Molar specific heat at constant pressure, Cp, is the amount of heat required to raise the temperature of 1 mol of a gas through 1K at constant pressure. Molar specific heat at constant volume, CV, is the amount of heat required to raise the temperature of 1 mol of a gas through 1K at constant volume.

How do you find the specific heat capacity of a metal?

Use Q = sm∆T to determine the heat capacity of the metal. (Make sure to use the heat given off by the metal, the mass of the metal, and the temperature change of the metal in this calculation.)

Is mercury flammable?

Mercury is non-combustible. The agent itself does not burn, but it may react upon heating to produce corrosive and/or toxic fumes. Fire will produce irritating, corrosive, and/or toxic gases.

Can you touch mercury?

If you touch it, a small amount may pass through your skin, but not usually enough to harm you. Mercury is most harmful when you breathe in the vapors that are released when a container is open or a spill occurs. Pregnant women, infants and young children are particularly sensitive to the harmful effects of mercury.

What do you mean by specific heat capacity of a is 910 J kg c?

Explanation: specific haet capacity is numerically equal to the amount of heat required to raised the unit temperature of unit mass of a substance. heat capacity means is numerically equal to the amount of heat required to raised the temperature of whole substance. A requires for unit change in temperature,910J.

Which metal has the highest specific heat?

Thermal capacity is the amount of heat required to increase the temperature of an object by one degree. The following table provides the values of the thermal capacity of some of the metals and Aluminum. It shows that Aluminum has the highest thermal capacity.

What material has highest specific heat?

What has the lowest specific heat capacity?

Metals tend to have low specific heat. Water has very high specific heat.

What do you mean by specific heat capacity of water is 4200 J kg C?

The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C. Some other examples of specific heat capacities are: Material. Specific heat capacity (J/kg°C)

Is 4.184 the specific heat of water?

The units of specific heat in the SI system are J/g-K. Because there are 4.184 joules in a calorie, the specific heat of water is 4.184 J/g-K.

What is the specific heat capacity of mercury?

Specific heat of Mercury is 0.139 J/g K. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics. The intensive properties cv and cp are defined for pure, simple compressible substances as partial derivatives of the internal energy u (T, v) and enthalpy h (T, p), respectively:

What is the latent heat of vaporization of mercury?

Latent Heat of Vaporization of Mercury is 59.229 kJ/mol. Specific heat, or specific heat capacity, is a property related to internal energy that is very important in thermodynamics.

What are the properties of saturated liquid mercury Hg?

Properties of saturated liquid Mercury – Hg – density, specific heat capacity, kinematic viscosity, thermal conductivity and Prandtls number: 1 kg/m 3 = 0.0624 lb/ft 3. 1 J/(kg K) = 2.389×10 -4 kcal/(kg oC) = 2.389×10 -4 Btu/(lb m oF)

Is Mercury a solid liquid or gas?

A liquid, silvery metal. Mercury has fascinated people for millennia, as a heavy liquid metal. However, because of its toxicity, many uses of mercury are being phased out or are under review. It is now mainly used in the chemical industry as catalysts. It is also used in some electrical switches and rectifiers.
