Here we use the equation ΔQ=mcΔT, where ΔQ is the energy change of the system, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the temperature change of the system. It can be rearranged to get c as the subject:
c=(ΔQ)/(mΔT)
Putting your known values into this equation yields an answer of 118Jg-1K-1.

What is the solubility of a metal?
Metals are not soluble in water; the chemical reaction with water is not solubility. Metals are soluble in acids; this solubility depends on the specific metal and acid, temperature, pressure, stirring, form of the metal, etc.
A metal that is solid at room temperature?
Most metals are solid at room temperature (20-30C)as room temperature is not enough to provide them required kinetic energy to overcome their forces of attraction or convert its state.thus,they remain solid at room temperature.
Do heavier metals heat up more quickly than lighter metals?
Yes. There is a property called 'specific heat capacity'. This is the amount of energy required to increase temperature of the substance by 1K. As you increase atomic weight, the heat capacity of the metal decreases. That means it requires less energy to heat up and so can heat up quicker. And this trend is not perfect, but still very pronounced. Here is a list of heat capacities of metals. If you were to rank these metals by atomic number, you would see a noticable trend.
What metals are solid?
At room temperature, all metals except Mercury are solid.
What is an element important in metal processing?
Sensors based on solid electrolytes have several advantages in the processing of molten metals. The conductivities of solid electrolytes increase with increasing temperature, so the high operating temperature required during the processing of molten metals is well-suited to solid electrolyte based sensors. A magnet is a material or object that produces a magnetic field. They offer us good help helping us separating metals from the trash.

What are unknown metals?
Today unknown metals doesn't exist.
Why does the temperature of the metal fall from its maximum after a while in a specific heat capacity of metals experiment?
because it can
What is the solubility of a metal?
Metals are not soluble in water; the chemical reaction with water is not solubility. Metals are soluble in acids; this solubility depends on the specific metal and acid, temperature, pressure, stirring, form of the metal, etc.
What is hot working of metals?
Hot working of metals is defined as a process of forming metals by deformation at temperature above the recrystallization temperature.
What metals are strong in room temperature?
Metals like steel are strong in room temperature. If you want anymore, search for metals as strong as steel :)
What is the state of matter that most metals are in?
That obviously depends on the temperature. At room temperature, most metals are solid.
At room temperature none of the metals are?
None of the metals are gasses at room temperature.
What temperature do metals melt at in Fahrenheit?
Mercury, which is liquid between -38.83 °C and 356.73 °C.
What metals are found naturally?
Not yet do many scientists know as some metals are formed unknown

What room temperature are most metals are in in?
Most metals are solids at room temperature. They're not liquids, and they're certainly not gases. Mercury is the only metal that is a liquid in this temperature range. There are 5 metals that are liquid at or close to room temperature. Cesium, Francium, Gallium, Rubidium, and Mercury.Almost all metals are solid at Room temperature and Pressure, except for Mercury, which is a liquid.
